When it comes to marine life, the Philippines has one of the most diverse in the region. Located in the “Coral Triangle”, The Philippines sits in the epicenter for the biodiversity of corals, fish, and other marine life in the world.

There are over 488 species of corals, 981 species of bottom-living algae, 5000 species of clams, snails, and mollusks that can be found in its waters. On top of that, over 3000 fish species have been recorded to be endemic to the Philippines.

The list of marine life in the Philippines keeps growing as more species are being discovered.

With such diversity, it is not surprising that the Philippines is considered to be one of the top scuba diving destinations in the world.

The marine life in the Philippines is astounding. Underwater photographers in particular love diving in the Philippines because of the amazing sea creatures one can find in its waters.

While there is “plenty of fish” in the Philippine sea, some sea creatures are more favored than others. They stand out because of their colors, behavior, distinct characteristics, rareness, and just plain awesomeness. Some are even more special than others that divers are even willing to travel hundreds of miles just to see them.

From large marine animals to small ocean critters, there’s always something new and interesting to see while diving in the Philippines.

Want to know what sea creatures in the Philippines do scuba divers have on their “Must-see Critters List”? Or do you need help with your fish identification? This article has a list of fish in the Philippines as well as marine invertebrates!

Saltwater Reef Fishes in the Philippines (27)

False Clown Anemonefish (Amphiprion ocellaris)

Sea Creatures in the Philippines- False Clown Anemonefish (Amphiprion ocellaris) in Bohol

This orange fish with white band outlined in black is one of the most popular fish in the ocean. You may know this one as “Nemo!” While anemonefish are very common to find in the Philippines, this Hollywood star can easily be the star in your dive. If you’re lucky you might even find a nest with hundreds of baby Nemos.

Pinnate Spadefish (Platax pinnatus)

Sea Creatures in the Philippines- Pinnate Spadefish (Platax pinnatus)

This is one of those species that undergoes a distinct transformation from its juvenile state to its maturity. As juveniles, the pinnate spadefish are completely black with an orange band running around the outline of its body. Then as adults, they become silver-colored, spade-shaped fish. It is a beautiful species in either form and a favorite subject by underwater photographers.

Bluetail unicornfish (Naso caeruleacauda)

Don’t believe in unicorns? Well, they do exist underwater! These fishes are hard to miss because of the distinct bony horn projecting from the head in front of the eyes. They’re said to be tasty so you might find local Filipinos grilling them for lunch.

Barramundi Grouper (Cromileptes altivelis)

Also known as “barramundi cod,” “flatfish grouper” and “humpback rockcod,” humpback groupers have very small, pointed heads and are light-colored with scattered, large, black spots. They’re listed as “vulnerable” in the IUCN list as they are targeted for live reef-fish trade. Unfortunately, if you do find one, it might be in the wet market or in some restaurant.

Bumphead Parrotfish (Bolbometopon muricatum)

Sea Creatures in the Philippines- Bumphead Parrotfish (Bolbometopon muricatum) in Apo Reef

The bumphead parrotfish, also known as humphead parrotfish, is the biggest parrotfish in the ocean. Their size and the distinct “bump on their head” make them stand out.

Pajama Cardinalfish (Sphaeramia nematoptera)

When you see these colorful fishes, you will understand why it was named as such. Their vibrant and distinct markings make them popular among divers. These sea animals found in the Philippines do appear like they are wearing pajamas. And it’s for this reason that they are popular among aquarium hobbyists as well.

Mandarinfish (Synchiropus splendidus)

Mandarinfish (Synchiropus splendidus) in Moalboal, Cebu

This dragonet has attractive blue, green, and orange wavy patterns on its tiny body, that catches the attention of many divers. But what makes them even more popular is the mandarin fish mating ritual dance which you can watch during a dusk dive in places like Moalboal, Malapascua, Southern Leyte.

Yellowbarred Jawfish (Opistognathus randalli)

Normally found with their heads poking out of sandy burrows, jawfish have huge mouths for the size of their head. Which probably explains their name. But what makes them even more popular is that the males are mouthbrooders. This means that the males incubate the eggs in their mouths for five to seven days until their babies are fully developed.

Magnificent Shrimp Goby (Tomiyamichthys emilyae)

The magnificent shrimp gobies are popular because of their large and beautiful first dorsal fin. They’re often found with their burrow partners, Randall’s pistol shrimp. This unique goby and shrimp pairing make them even more interesting underwater subjects to observe and photograph.

Oriental flying gurnard (Dactyloptena orientalis)

Oriental flying gurnard, also known as flying fish, grunt fish or sea robin, are reef fish that has large pectoral fins that look like wings. Their fins are usually against their body but when they threatened they expand their pectoral fins to scare of predators. They have been observed “walking” on the ocean floor using their pelvic fins. And they also “grunt” thus the name gurnard which means to grunt in French.


Frogfishes are among the most popular marine life in the Philippines. These weird-looking but wonderful creatures are great in hiding or blending in with the reef that when divers spot them its always a delight.

While they can be found almost everywhere, if you want higher chances of seeing them then Dauin is the place to go. It has been called the “frogfish capital of the world” with 11 frogfishes species being spotted in the area.

Here are some of the frogfish species that can be found in the Philippines:

Giant Frogfish (Antennarius commerson)

Sea Creatures in the Philippines- Giant Frogfish (Antennarius commerson) in Bohol

The hairy frogfish is not actually hairy. Their body is actually covered in spinules or skin appendages that look like strands of hair.

If you love frogfishes, you might also want to check out the PADI Frogfish Specialist course that is exclusively offered in Dauin.

Napoleon Wrasse (Cheilinus undulatus)

The Napoleon wrasse (Cheilinus undulatus), also known as the Māori wrasse, hump head wrasse, get its name from the distinctive hump on its forehead, which resembles the hat of the French emperor Napoleon Bonaparte. Napoleon wrasses are known to grow up to 2 meters long (6feet) and have beautiful green scales. They are popular marine life in the Philippines not just under the sea but also in dinner tables. Locally called “Mameng”, wrasses are also endangered species in the Philippines because of overfishing for their meat.

Weedy Scorpionfish (Rhinopias frondosa)

While scorpionfishes are very common to see in the Philippines. The weedy scorpionfish (Rhinopias frondosa) are a bit more rare to come by. Or at least harder to spot.

These marine life in the Philippines are masters of disguise. The weedy scorpionfish looks like rocks covered in algae. Their appendages look like they are covered in weed so they easily blend in. Rhinopias come in dark red, purple, yellow or lavender, making them appear like soft corals or sponges to an untrained eye.

Red Lionfish (Pterois volitans)

Philippines Red Common Lionfish (Pterois volitans)

Red Lionfishes are commonly found in the Philippine. They’re very pretty to look at especially when they spread out their spines. But you should keep your distance as they are venomous. While they are endemic in the Indo-pacific area they are considered invasive species in the Carribean and Atlantic regions. Lionfishes are popular in the aquarium trade and this may have caused the spread of this invasive species in other reefs in the world.

Crocodile Flathead (Cymbacephalus beauforti)

The Crocodile Flathead is closely related to scorpionfishes. As their names suggest they menacingly look like crocodiles! Their body is covered in mosaic patterns of beige, brown, green, gray, which helps them blend in their habitat. They’re commonly found resting on rubble or sand.

Whitemargin stargazer (Uranoscopus sulphureus)

Sea Creatures in the Philippines- Whitemargin stargazer (Uranoscopus sulphureus) Puerto Galera

Stargazers are bottom-dwelling predators often found burrowing in the sand with only their eyes protruding. So they do look like they are always gazing at the stars. Their mouths are almost at the same level as their eyes so when an unsuspecting creature swims over them they could easily be devoured.

Yellow Boxfish (Ostracion cubicus)

Sea Creatures in the Philippines- Yellow Boxfish (Ostracion cubicus)

The Ostracion cubicus easily stands out in the reef because of its box-shaped body and yellow coloration. The yellow boxfish at its juvenile stage is bright yellow with black spots. As it matures, its color becomes light yellow with blue-gray colorations.

Striped Eel Catfish (Plotosus lineatus)

Dangerous Marine Life in the Philippines Striped Eel Catfish (Plotosus lineatus) in Romblon

The striped eel catfish often catches a diver’s attention because of their black and white stripes and their schooling behavior as juveniles. To protect themselves from predators, they form a cluster of of up to a hundred catfishes. But don’t let these seemingly harmless fishes fool you, their dorsal and pectoral fin spines are actually highly venomous and can inflict you pain.

Titan Triggerfish (Balistoides viridescens)

Dangerous Marine Life in the Philippines Titan Triggerfish (Balistoides viridescens)

The Titan Triggerfish, also known as Moustache or Giant Triggerfish, is the largest and most aggressive of the Triggerfish. They are notorious among divers because they’re known to attack especially when it is their nesting season. Best to stay clear of these creatures as there probably have been more cases of Titan triggerfish bites than shark attack!

Spot-fin Porcupinefish (Diodon hystrix)

Spot-fin Porcupinefish (Diodon hystrix) in Apo Reef

The spot-fin porcupinefish is a kind of pufferfish with spines. Its body coloration is beige marbled with dark blotches and dotted with numerous black spots. When it senses danger or when it is stressed, the porcupinefish can inflate itself by swallowing water. It will “puff up” into a balloon with its spines raised to prevent predators from consuming it. The pufferfish has poison that if consumed can kill humans. This, however, does not deter them from eating it. In fact, some catch it as they are considered delicacies.

Ocean Sunfish (Mola mola)

The Mola mola is one of the heaviest known bony fishes in the world. The Ocean Sunfish got its name from its behavior of going to the surface then swimming on its side to bask in the sun. Many provinces in the Philippines have reported Mola mola sighting and stranding which is why it’s made it to this list of popular marine life in the Philippines.

Big Eye Trevally (Caranx Sexfasciatus) 

School of Jacks in Balicasag - Big Eye Trevally (Caranx Sexfasciatus)

The Big Eye Trevally (Caranx Sexfasciatus) is truly a sight to behold when these silvery fishes start swimming in a circle creating a giant bait ball. Make sure to keep your “big eyes” out for these school of jacks. They can be spotted in Balicasag Island.

Battery is what you call a school of Barracuda!

While the Great Barracuda (Sphyraena barracuda) tends to be a solitary creature, the blackfin barracuda is usually seen as a group. They’re also known as chevron barracuda because of their black markings along its body. Aside from their distinct markings and schooling behavior, they’re known for their speed and razor sharp teeth.

School of Sardines

However, many divers have successfully spotted them in one of the most successful and largest marine protected areas in the Philippines- Tubbataha Reefs Natural Park.

Philippine Guitarfish (Rhinobatos whitei)

If a shark and a ray had a baby it would probably look like a guitarfish! Also called a banjo shark or fiddler ray, guitarfish have a flattened fore-body resembling that of a ray and a hind-body resembling that of a shark. In 2014, the Philippine Guitarfish Rhinobatos white, an endemic marine species in the Philippines, was recognized as a new species belonging to the Rhinobatidae family.

Scalloped hammerhead (Sphyrna lewini) 

While hammerhead sharks have been spotted in the Philippines, in recent years sightings has been more rare. Unfortunately, despite Philippine laws prohibiting the capture of these endangered species, there might even be a greater chance of you seeing hammerheads in the wet market than in the ocean. In the past scalloped hammerhead sharks have been seen in places like Malapascua in Cebu, Cabilao in Bohol, Apo Reef in Mindoro and Tubbataha Reef in Sulu Sea.
