Diving with…Andrea Agarwal, Thresher Shark Divers, Malapascua, Philippines

In this ongoing series, we speak to the people who run dive centres, resorts and liveaboards from around the world about their businesses and the diving they have to offer…
Andrea Agarwal
What is the name of your business?
Thresher Shark Divers
What is your role within the business?
Owner/Managing Director/Marketing and Reservations
How long has the business operated for?
15 years
How long have you dived for, and what qualification are you?
20 years, PADI Master Instructor
What is your favorite type of diving?
Muck diving. And of course, sharks!
If you could tell people one thing about your business (or maybe more!) to make them want to visit you what would it be?
Thresher sharks! Malapascua is the only place in the world where you can have up-close and personal sightings of this magnificent creature every day!
What is your favorite dive in your location and why?
My favourite dive site is Gato Island. Whilst I adore the sharks, I love my macro more and I originally settled in Malapascua because there is so much macro at every dive site. But Gato outshines them all and has a superb variety. When I arrived on Malapascua in 2003, I coined the phrase, “You come for the sharks, but leave remembering Gato,” and we still use that today.
You can see assorted seahorse including pygmies, so many species of nudis, crustaceans of all sorts, several frogfish species, and so much more. And it’s not just macro. There are beautiful soft corals, as well as bigger stuff like the mesmerising mating cuttlefish that I could spend all dive watching, and Gato’s famous tunnel under the island, often with whitetip sharks inside! If not, you will definitely see whitetips hiding under rocks and you can get very close up as they open and close their mouths ominously! (Don’t worry, they’re only breathing!)
What types of diving are available in your location?
Sharks and large rays; wrecks and reefs; wall dives and muck dives; beautiful coral gardens, mating mandarin fish, and amazing macro.
What do you find most rewarding about your current role?
I adore working in an industry where you exist to make people happy and make their dreams come true. There is nothing I love more than hearing that someone has had the most amazing holiday of their life! And when diving, there is nothing better than finding some new weird and wonderful creature I’ve never seen before. For example, I’m still on the search for that elusive Bobbitt Worm, and I’m hopeful I will find it one day! They simply have to be in Malapscuan waters!
What is your favorite underwater creature?
Oooh, so difficult to choose!!!
I think I’d have to go for the aforementioned cuttlefish (although you might get a different answer tomorrow!). They are so intelligent, so beautiful to watch, especially when they are flashing full colours when mating, and with enough patience, once they get used to you, you can even play with them (no touching of course!)
Are there any exciting changes / developments coming up in the near future?
We saw a tiger shark this week for the first time ever at Monad Shoal, the thresher shark site! Hoping it will be the first of many sightings!!!
As a center what is the biggest problem you face at the moment?
That’s a toughie as there are many! The main issues have been ongoing for forever, and include things like waste management and marine protection. Although I’ve tried, it’s impossible to do anything meaningful without government help.
Is your center involved in any environmental work?
Yes, we always have been. We were one of the first dive shops on Malapscua, and since I first arrived, I’ve pioneered marine protection initiatives. Off the top of my head, among other things, I wrote and implemented the rules for diving with the sharks, have organised removal of hundreds of thousands of crown of thorns during two separate infestations (not a problem now thankfully), and tried to implement a program, funded by business donations, to install litter bins and employ locals to keep the island clean.
For these larger scale issues, it’s an uphill struggle, especially with increasing tourism, and it requires governmental help to succeed… Some things are easier to control – of course we do regular clean-ups, we always insist on proper dive practices to protect the environment, we have a very strict no gloves/no touching policy etc. etc.
How do you see the SCUBA / Freediving / snorkeling industry overall? What changes would you make?
I wish there was a way to weed out the cowboys. I hate hearing stories of bad experiences with bad dive shops who cut corners to save a buck, or lazy Instructors and DMs who just can’t be bothered and end up giving divers frightening experiences. I’ve always run Thresher Shark Divers with a strong motto of “Safety and quality first”, and in that order. Our reputation reflects that and I’m very proud of my team for always supporting me in this, and upholding my values.
What would you say to our visitors to promote the diving you have to offer?
“Safety and quality first”!!!
Joking aside, this is our other tag line-
“You want big fish? We got big fish!
You want macro? We got macro!
You want wrecks? We got wrecks?
You want it all? We got it all!
Malapascua Island – your one-stop dive spot!”
I wrote that not long after we opened, because I did and still do believe it with a passion. I settled on Malapascua because of the tremendous variety of diving – the dive sites are spread out in all directions, with all kinds of oceanic influence, and it means they mostly have very different kinds of diving.

Ultimate Raja Ampat – The Last Paradise (Part 3 of 3)

When you visit a place like Raja Ampat over 11 days you really have a lot to talk about. The biodiversity and landscape of the region are inspiring and this is why it’s taken me three blog articles to explain how wonderful this experience was. If you haven’t had the chance already to read the previous two blogs, you can find them here: Part 1 and Part 2.
After a crossing of around 14 hours – quicker due to a southerly current working with the boat – we found ourselves in Farondi diving Razorback Rock, Anchovy, Nudi Rock (yes, it looks like a nudibranch) and a night dive at Yilliet Slope. I have to admit, it was the south and around Misool that I was really looking forward to on the trip, but it didn’t really get off to the best start and never lived up to the high standards further north had set. To be frank, this was more down to the weather really and the visibility wasn’t brilliant.
A storm meant the dives were pretty dark and in fact, the dive at Anchovy in particular was more like a night dive than a day dive. Unfortunately, we can’t control the weather and on other days these sites could have delivered a lot more. The sea fans on each dive were equally as impressive as further north, and I’d probably say more abundant. The dark atmosphere did mean I could try some fun and different shots with clownfish in anemones but I probably should have switched to macro quicker that day. There are always fun critters to find on every dive site and Nudi Rock showed just that, with a few sea fans being infested with skeleton shrimp. While I’ve seen skeleton shrimp before, I’d never seen anything like this; every bit of the fan was covered. There must have been thousands and it was quite fitting that it was actually Halloween as well.
After a moody day, where I’m guessing the weather gods were celebrating Halloween, I finally switched to macro on the night dive and my photography was rewarded for it. An elusive pygmy squid started the dive but didn’t allow me to get a photo with its tricky movements. Still fun to watch and see, before once again, nudibranch were the stars of the show. A free swimming black and orange flatworm mesmerised mid-water, but it was a super tiny nudibranch of only around a centimetre long that I admired most and took some time to photograph. Then it was the turn of crustaceans once again. A couple of different types of decorator crab, a couple of lobster species and a whip coral shrimp finished off the dive after the sea slug starter.

It was a fun game of dodge the jellyfish on the dive at Four Kings. Such a unique experience for me on a dive
The next day, the wide-angle opportunities improved drastically. Although, rather annoyingly, I stuck with macro on the first dive at Neptune’s Fan Sea. I hadn’t seen a Denise pygmy seahorse before and was desperate to get a shot of one before the trip was over. This site was a great opportunity. It was sea fan heaven, but that does mean there’s a lot more places to look. The topography was incredible on the dive, a cliff of sea fans greeted us and made wide angle a good option. It was such a relaxing dive with a small school of bumphead parrotfish making the occasional pass, and the soft coral formations continued in huge numbers and were so impressive. I did manage a couple of nice nudibranch shots but the seahorse remained elusive for our group.
I decided to switch back to wide angle for Four Kings and that was certainly the right choice. A swarm of jellyfish greeted us on the dive and made it one of the most memorable of the trip. There was so much life around the pinnacles as the fish life danced a merry dance. The game of dodge the jellyfish entertained throughout and it was interesting to see as they’d get trapped on the sea fans. Something I’d never experienced before on such an incredible dive site. Barracuda point finished off the day’s diving in relaxing style, with a stunning top reef. Yes, I saw my first two Denise pygmy seahorses here, but no, I had my wide angle on. It was a great site for photographing lionfish though and there was a small school of barracuda giving the site its name.
Although “The Jellyfish Dive” was an amazing highlight of the day, it wasn’t actually diving that finished the day in style. A sunset cruise in Wayilbatan delivered those feels. You know the ones, when you’re in a beautiful place, at a beautiful time and with only a handful of people. You get that completely content feeling and just forget all your worries and live for that moment. It was a spontaneous trip out as well, as the itinerary was to trek to Love Lagoon. However, the guests on the trip before advised it would probably be best to take it off the itinerary for a bit. Unfortunately, with a forced Covid break and lack of maintenance care, the stairs have become slightly dangerous for trekking. The alternative didn’t disappoint and in fact excelled. An exploratory journey, where even the crew didn’t really know where we were going, took us to some breathtaking views with an amazing sunset backdrop. The glass like sea provided the perfect stage with its mirror like reflections. Then in the shallows we could see every bit of coral and life we passed, before tilting your head and following the cliff face up to amazing limestone islands covered in lush green rainforest. Just beautiful!!
With only two days and six dives left, one of my main goals was to photograph a Denise pygmy seahorse. I was in a catch 22 though, there were some memorable wide-angle dives to come. Starting with Boo Window and the arch swim through creating a dramatic image with a diver. I was happy with those wide-angle photos, but guess what? We did see a pygmy again. Still, I wasn’t to be defeated and we also had the friendliest hawksbill turtle on the dive too.
Next up was Shadow Reef (a.k.a Magic Mountain), in the hope to see the majestic Oceanic manta rays. We entered through a concentrated section of bad visibility and then the weather also changed with a storm passing over while we were below. It went dark underwater once more and unfortunately there were no mantas to be seen during the dive. It was still such a special dive site with schooling jackfish, a small school of batfish, another friendly hawksbill, Napoleon wrasse and my first whitetip reef sharks of the trip.
I had to switch to macro and hope for a pygmy at Whale Rock. No such luck unfortunately, but it was an amazing macro dive with numerous crustaceans and my favourite photos of whip coral shrimp. A Pikachu nudibranch was another great nudibranch find by one of my dive buddies. There might have been no seahorse due to skeleton shrimp infesting all the sea fans, but I was really happy with the macro photography success on this dive.
The night dive at Romeo carried on with the magnificent macro theme. We were there to try and see a walking shark again but unfortunately it remained elusive on this dive. Typical, when I have all my equipment working! However, a friendly cuttlefish, some pygmy squid and more crustaceans made the dive memorable still. Can I get to photograph a Denise pygmy with only two dives left?? I really hope so…
We finished our diving in Raja Ampat at Tank Rock and Boo West. I was advised both dives would be preferably wide angle. I knew I needed to stick to macro though, with seeing three Denise pygmies previously while shooting wide angle. I didn’t want to miss the opportunity before I left Raja Ampat. Then, as the dive started, I began to lose hope once again. Skeleton shrimp filled the sea fans once more and I thought that would be enough to scare any seahorse to another site. BUT!! It wasn’t long before my guide Aghi worked his magic and found a beautiful little Denise pygmy seahorse for me to photograph. Phew!!! The pressure was off for the dive early on, but now I just needed to get a photo of these difficult to photograph critters. Skeleton shrimp were still sharing the sea fan with the seahorse and parts of them tended to get in the way but without a nice composition of both. I did manage to get some decent in focus shots and my diving in Raja Ampat was complete. Mission successful for another new species for me. An orangutan crab and some nice photos of the skeleton shrimp completed the dive before a switch back to wide angle for Boo West.
While the visibility wasn’t great (but not terrible) for the final dive, it was another stunning dive in paradise, with once again amazing sea fans littering the reef wall in pristine condition. Then came my favourite schooling fish to see, as what must have been around a hundred batfish/spadefish were seen cruising in the current. Such an amazing sight, with a couple of blacktip reef sharks also coming to say goodbye. The real surprise and the memorable moment of the dive came from a tiny cuttlefish that was just bobbing around in the blue away from the reef. I really wasn’t expecting to see it there, as I caught it in the corner of my eye. It took me a second to confirm I wasn’t seeing things but sure enough it was there. It was super friendly and came right up to my mask and I can only hope it stayed safe away from the protection of the reef once we left.
I’d been desperate to visit Raja Ampat for so long and thankfully it didn’t disappoint. La Galigo was the perfect vessel, with the perfect hosts to explore the area with that really made my time extra special. It’s certainly a place I won’t just want to visit once. I could see myself returning again and again and still being amazed by all the things I’d see. I ticked off so many new species in this biodiversity hotspot and took countless photos.
I now had a long journey home of two days, with 22 hours in Jakarta airport. I wasn’t fazed though, as I had so many photos to go through to keep me entertained and those memories kept me smiling throughout the journey. I’d recommend everyone (not just divers) to put Raja Ampat on your travel bucket list. It really is a true paradise and I can perfectly understand where the nickname – “The Last Paradise” comes from.

Ultimate Raja Ampat – The Last Paradise (Part 2 of 3)

I’m hoping by now that you would have read the first part of my Ultimate Raja Ampat story with La Galigo Liveaboard. If not, then please check out Part 1 HERE. We really started with a bang and visited some incredible dive sites in the first few days. The amount of fish life seen on the dives was incredible and I could only hope the rest of the trip would continue to deliver.
I didn’t have to wait long before another unforgettable dive for the very first the next day. We were aiming for ‘Manta Ridge’ and as the name suggests, we were looking for the majestic manta rays. The anticipation was bursting as I love spending time with manta rays and the guides had already alluded to the fact they saw them on the current check. The current was strong and reef hooks were advised once we got to the ridge.
My group was the last in and as we worked our way along the ridge towards the cleaning station, it wasn’t long before a manta came into view. I managed to find a great spot to hook into and enjoyed the most amazing show. Stunning reef manta rays glided over my head within touching distance before hovering over the reef as they were cleaned thoroughly by black lip butterflyfish and other small fishes. This was how we spent most the dive at around only 10 metres before moving back along the ridge and shallowing up on top of the reef to hook in for our safety stop. HOWEVER, the best was yet to come for me personally, as I was reluctant to leave and dawdled behind the group, continually checking over my shoulder, until there it was…
This was what I was hoping to see on my trip to Raja and to be close enough to get a photo I was truly happy with. I’d seen black manta rays before, but never close enough for a decent photo, now suddenly the opportunity presented itself. I saw my group just metres away hook onto the reef at 5-6 metres and I felt protected from the worst of the current, as this majestic manta suddenly glided within just a couple of metres of me. I couldn’t believe the interaction I was getting and it felt like I was completely alone with it for this short moment. It glided along the reef while getting cleaned before circling a couple of times within touching distance. I just kept shooting and hoping the photos were coming out ok, while my adrenalin was pumping through my body for one of the best manta ray encounters I’ve had. Thankfully I was more than happy with the images I got and the memories were even greater.
It was only day four and I had already ticked off some real Raja Ampat bucket list moments. The pressure was certainly off but the day continued in style and showed the diversity of life here. After a second dive at Mayhem with numerous resting wobbegongs and an overly friendly hawksbill turtle, it was time to mix it up on the third dive and go small, really small. Raja Ampat is famous for pygmy seahorses, as it’s an incredible place for numerous healthy sea fans. I’d been advised you have the chance to see them on pretty much every dive, making it so hard to choose between macro and wide angle with the incredible choice here. For dive three though, I was advised Hippocampus bargibanti had been seen on the previous trip and I opted for macro. It didn’t disappoint and I was so happy to see the super cute bargibanti seahorses once again and have the chance to photograph them. Followed by one of my favourite critters no matter how many times I see them – the peacock mantis shrimp. I love it when a plan comes together!!

Wayag Lagoon trek was quite the adventure as we scrambled from the speedboats onto the limestone island
It was now time to head to the most northern part of the itinerary – Wayag. Famous for its stunning landscape and lagoon, I was really looking forward to mixing it up and taking a break from diving. Our first adventure of the day would be a trek up Wayag Lagoon instead of diving, although I couldn’t resist a quick swim with the blacktip reef sharks that were circling the boat before the trek.
The trek in itself was an interesting adventure. I wasn’t expecting it to be difficult and presumed it was stairs but I soon realised it wouldn’t be that easy. It made it much more fun though, as we navigated the footholds and scrambled up the formations in the limestone. The limestone can get quite sharp and you really have to have your concentration in check on this climb, but it is more than manageable for any fitness level if you take your time. It is only a short 20-minute hike but took longer due to being mesmerised by the incredible views with each step higher. One of the most stunning views I’ve been lucky enough to lay my eyes on. The different shades of blue of the glass like sea broken up by lush green rainforest covering the limestone islands. It’s so cliché to say “the view took my breath away” but there’s no other way to describe the scene.
Diving around Wayag was all about macro critters for me. Two more day dives followed where again nudibranch of all shapes, size and colour made appearances. Our guide Aghi was brilliant at finding the really small flabellina variety. Squat lobsters, crabs and shrimps were the crustaceans keeping me entertained before one of the best night dives ever. Terserah Point is a sloping white sand dive looking for the weird and wonderful. Bobtail squid were seen in great numbers and were another first for me, with a long arm octopus, cuttlefish and decorator crab also putting on a show before the grand finale. The charismatic coconut octopus dazzling with its colours and tentacle show, while trying its best to hide between two shells. Again, another first for me, which was becoming quite the norm on this trip. Even having a close call with a box jellyfish right at the end of the dive, it got the adrenalin going but again another cool critter to see and my first.
The next couple of days we started to head south again, as we were aiming for the area around Misool Island and the marine reserve. We stopped at Kawe, Aljuy and Penemu along the way and the dives were all about the stunning coral that Raja Ampat is famous for. While also trying to see manta rays again at Eagle Rock 1. Unfortunately, the dive didn’t deliver mantas, although it was a stunning site with hawksbill turtle, wobbegong and the only banded sea krait I saw on a dive on the trip. However, we just happened to be diving the wrong island at Eagle Rock and when we surfaced, we saw mantas from the boat and took the opportunity to swim with them as six swam past at the surface. One bigger manta continued to circle a coral pinnacle beneath us – enough for another manta fix!
The swim throughs at Wofoh South and Batu Rufus provided stunning photography opportunities with amazing topography. The dancing anchovy school mesmerised, and the coral formations were breathtaking on all dives, none more so than the beautiful Melissa’s Garden. This was a relaxing dive on top of some of the best hard coral gardens I’ve seen. Anthias danced in and out with Napoleon wrasse a constant sight throughout. It was also another amazing dive for nudibranch, quite the popular macro subject in Raja Ampat. Pianemo trek on the morning of day seven was again a welcome break from diving and something different to enjoy and see the amazing scenery from a vantage point. A much easier trek, as a well-maintained staircase leads you up to the viewpoint over the lagoon. Breathtaking views were waiting, while meeting local villagers and buying fresh coconuts provided welcome company from our liveaboard bubble.
While all these sites were truly special, it was again the night dive that stole the show for me. Another sloping white sand dive but this time at Wofoh North. Again, it was all about the weird and wonderful, as the guides alluded to it being a great place for wunderpus octopus. I was keeping my fingers crossed, as it was another new species for me to see and as it happened, I didn’t have to wait long into the dive. There it was, sitting perfectly still in the sand, no bigger than the palm of my hand and guess who found it? Yes!! That’s right! I was so excited to spot it in the sand myself, although it took me a second to make sure it definitely was an octopus. What an amazing dive this was for the whole 50 minutes. Another wunderpus was found, that was actually still in its larval stage; an amazing find. Spearing mantis shrimp, nudibranch, sea moths, bobtail squid, devil scorpionfish and more were just the tip of the iceberg on another amazing night dive.
This place just continued to deliver with its amazing biodiversity and it was now time to head south on a 16 hour crossing heading close to Misool Island. Stay tuned for our adventures on the final four days diving the south.
