Cantagay Marine Sanctuary: Home of a Spectral Secret

Black Corals

It is a privilege to see something rare in Mother Nature. That treasure, which only a select few has laid eyes on, makes us realize that there are so many things in this world that we simply don’t understand. For us, that experience is something humbling, something spiritual. Under the blue waters of Jagna in Bohol, a seldom seen spectral wonder touched our souls.

A gentle sunrise, the orange glow of a beautiful day, and an almost glass-like calmness over the Bohol Sea promised an excellent day of diving. Even from the perch of our room in Mahrjun’s Apartelle, we could clearly see rock and coral formations underneath the blue waters.

Cantagay Marine Sanctuary

After eating a filling breakfast and preparing our dive gear, we went straight to Drift Divers in Paseo del Mar Resort. Because Jagna is a relatively untapped diving destination, no other diving outfitter has set up shop in town. Thus, Drift Divers enjoys itself as the sole dive center in Jagna.

Drift Divers

Owned by a chatty and pleasant Italian immigrant named Sylvio Eandi, Drift Divers is a well-equipped, warm, and friendly outfit. The bamboo, wood, and nipa office, accentuated with traditional furnishings and decors, are very Filipino. Anyone feels as if he or she is stepping into a welcoming home rather than a cold business establishment.

Drift Divers

The exterior of Drift Divers is even more comfortable. For a start, the entire facade of Paseo del Mar faces the sea, feeding guests with a continuous view of a lovely seascape. Lay down on one of their bamboo lounge chairs, and you will be lulled to a lazy snooze in minutes. You will feel your stress blown away by the gentle sea breeze.

Jesse Acebes, the owner of Paseo del Mar, has built a nice gazebo where guests can relax. He plans to repair the bridge that leads to it; the bridge was destroyed during a recent storm.

Paseo del Mar

After meeting our PADI Dive Instructor Jason, we headed to our boat, a small Bantay Dagat patrol boat. Sylvio said that his own dive boat was still being docked for regular maintenance. Sheila, Edgar, and I were as excited as the Bantay Dagat personnel who were assigned to escort us.

And off we go to our dive site! Bantay Dagat personnel keep on the lookout for illegal fishermen who hunt for fish, shellfish, and other marine flora and fauna inside the protected marine sanctuary that lines up Jagna’s coast.

Bantay Dagat

Which brings us to one of the best things about diving in Jagna. Because a gigantic reef is just situated a few hundred yards offshore, divers don’t actually need to hire a boat. They simply need to ride Drift Divers’ multicab since the highway is right along the shoreline. Believe it or not, shore entry is the most convenient way to explore the dive sites of Jagna.

Jagna Coastline

Locals are still allowed to fish but not in the protected areas. Thus, they need to sail a little bit farther than their usual fishing grounds.

Cantagay Marine Sanctuary

While most of Jagna’s coastline is relatively flat, parts of it are broken by high and magnificent sea cliff such as these. These are home to various sea birds, reptiles, crabs, and other creatures that call the sea their home.

Sea Cliff

We arrived at the Cantagay Marine Sanctuary around 15 minutes later. To our pleasant surprise, the dive site was actually just a short distance from Mahrjun’s Apartelle where we were staying for the past three days.

After donning our dive gear, we back-flipped into the water and was immediately greeted by an immense field of beautiful and healthy corals. It is reminiscent of the coral fields in the Chapel Dive SiteΒ in Apo Island.

Cantagay Marine Sanctuary

Moose horn corals are plentiful in the Cantagay Marine Sanctuary. They have this nice, gentle shade of periwinkle.

Moosehorn Corals

Where there are healthy corals, there are lots of fish. Five minutes into our dive and we saw massive schools of damselfish, assessors, Moorish idols, tangs, and more. It’s an entire biological metropolis in here!

Cantagay Marine Sanctuary

We also spotted this large and handsome brain coral. Brain corals are reef builders and can grow as large as 6 feet in height. They can live up to 900 years! Because of their spherical shapes, they can resist strong currents better than branching corals.

Brain Coral

The Cantagay Marine Sanctuary is a double reef, the first we’ve ever seen. As its name implies and as you can see in the photo below, a double reef is arranged as layers like shelves. The second layer of reef hangs just underneath a short kantil.

Cantagay Marine Sanctuary

We had a funny encounter with a gentle denizen of Cantagay Marine Sanctuary as we descended towards the bottom. This young hawksbill turtle was resting happily on the corals as we approached her from behind. I tried to approach her quietly so I can take a better photo of her. Unfortunately, the bubbles from my regulator startled the turtle, and she swam away as fast as she could.

Poor turtle. Sorry for disturbing your nap, girl.

Hawksbill Turtle

Jason guided us 110 feet down into the deep blue; this is the deepest we’ve ever dived. The short kantil gave way to a gradual sandy slope. Beyond that, we saw a mysterious, spectral—something. By all accounts, the figure looks like a hideous, shapeless ghost, its arms outstretched beneath its tattered, diaphanous cloak.

Black coral

As we moved closer, we left our supernatural assumptions—and fears—behind for we know that we have laid eyes on the secret and prized treasure of the sanctuary. We have come face-to-face with rare tree-like black corals. These are deep-dwelling corals that thrive 100 feet or more below the water.

Black coral

We studied one clump of such corals up close. Judging from its shape and its location in the tropics, these black corals most likely belong to the genus Antipathies of the Antipathidae family. They grow in depths of 10 to 400 meters below the ocean’s surface.

The coral’s living tissue (its polyps) is brightly colored, but its branching skeleton is black or dark brown, earning the species its namesake. They were once harvested as semi-precious gems. Deep-diving fishermen would pluck them off their perches, shave off the white polyps, dry the skeletons, and sell them as decorations or jewelry.

Poaching them is now prohibited since black corals are listed in Article II of the Convention on International Trade in Endangered Species (CITES) as an endangered species.

Black Corals

The rough texture of the black coral skeletons make them favorite perches for several marine creatures. Barnacles and crinoids attach themselves to the rough surface.Β During our dive, we found a small colony of pearl oysters glued at the bottom of the coral’s trunk.

On whip black corals (which are also found in the sanctuary), gobbies and damselfish bite off small sections of the skeleton to create nests for their eggs.

Pearl-producing oysters

A blue multi-limbed sea lily attaches itself to a thick stalk of a black coral. A sea lily starts out as a free-swimming feather star. But once it finds a suitable surface, it grows a stalk to anchor itself to that surface. Sea lilies look like plants, but they are actually animals.

Sea lilies are filter feeders, catching plankton and bacteria with their feather-like arms. Certain species of sea urchin feed upon the lilies, but the latter may evade predators by breaking off from their stalks and swimming to safety.

Sea Lily

It was quite strange seeing an anemone and its colorful clownfish residents this deep. Normally, we encounter them on the shallower parts of the reef.

Anemone Fish

This strange creature is a stichopodid, a species of sea cucumber. And it’s a big, fat one at that; this specimen is easily more than a foot long! We guess it did not feel threatened because it did not regurgitate its cuvierian tubules—sticky white threads that entangle or surprise predators.

Sea cucumber

Jason motioned us over and pointed at something with his metal probe. At first, we thought he was just indicating a fat starfish. But upon closer look, he was actually pointing at a black and blue nudibranch. At more than an inch long, this one is quite large.

Nudibranches, often called sea slugs, are sea mollusks without shells. They are popular subjects for underwater photographers due to their beautiful colors and interesting forms. Marine biologists have identified over 2,300 species of nudibranches worldwide.

Starfish and nudibranch

We couldn’t stay long in deep water due to nitrogen build-up in our circulatory system. So we slowly made our way back to shallow water at 50 feet. Once again, we were surrounded by forests of soft and hard corals. That’s a nice bridge for fish to play in. Then we noticed a lot of blue dameselfish are congregating in that spot. What could it be?

Well, it turned out that we just came upon a cleaning station. A cleaning station is an area in a reef where fish, turtles, and other aquatic life congregate so they could be cleaned by smaller creatures, notably bluestreak cleaner wrasses and cleaner shrimps.

You see, tiny ectoparasites latch themselves on fish, causing discomfort, itching, and infection. Since fish do not have fingers to pluck these parasites off, they head to a cleaning station where wrasses and cleaner shrimp eat off the parasites, dead skin, and scales. The benefit is mutual; the fish get a shower while the cleaners get a nutritious meal.

Cleaning Station

The Cantagay Marine Sanctuary is one of the richest reefs we’ve ever seen. But we know that we just uncovered a few of its secrets. According to Jason and Silvio, and further attested by Drift Divers’ Facebook photos, there has been sightings of whale sharks, reef sharks, sea snakes, moray eels, schools of jackfish, and more. There are even rare and well-camouflaged conch shells thriving here.

Cantagay Marine Sanctuary

As usual, action speaks louder than words. Or photos. So we included a short video of our dive. Check out the startled turtle. Hehehe!


Non-divers can enjoy the marine sanctuary as well. Similar to the Colase Marine Sanctuary in Samboan, Cebu, the reef begins just a few hundred feet away from the shore. This was where our non-diver companions were swimming around when we finished our dive.

In just 5 or 6 feet of water, snorkelers can witness the revelry of Jagna’s underwater kingdom.

Cantagay Marine Sanctuary

Immense table corals form like living arenas in shallow waters. Like most corals, they are solar powered, using photosynthesis for food production.

Table Coral

Lettuce leaf corals are usually mistaken for plants. They are susceptible to bleaching due to their extreme sensitivity of changes in water temperature.

Lettuce Coral

Swimming, diving, and snorkeling all morning can really take its toll on one’s tummy. Thus, after having our fill with diving and snorkeling, we went back to Paseo del Mar to enjoy a delicious buffet lunch. The tinola was superb!

Special Thanks

We would like to thank Silvio Eandi, the owner of Drift Divers, for letting us explore and enjoy his playground. This Italian fellow, who is never without his dog Gigi, is very friendly and accommodating. His various tales from his homeland and in Jagna are absolutely worth a day and/or night of cold beer! He will ensure you have a great dive and a fun time in town.

Lastly, we would like to thank our reader Jeremy Horowitz for the detailed information about black corals. Jeremy is a marine biologist and ecologist based in James Cook University in Queensland in Australia. He regularly visits the Philippines for coral research, nursery establishment, and more.

Seldom-seen black corals, vulnerable and endangered marine life, and other uncommon wonders of the sea have found a home in the Cantagay Marine Sanctuary. The virgin beauty of this place is truly astounding. Now, it is up to us—locals, visitors, divers, the LGU, and everyone who loves Mother Nature—to protect the inhabitants of this underwater world from becoming true specters.

Aside from dive adventures, they also offer PADI certifications of all levels.


1. For optimum visibility, it is best to dive in the morning when the sun is shining and at the right angle. At times, a gentle current stirs up the silt, but it’s not really that bad that it obscures your visibility.

2. The Cantagay Marine Sanctuary is only one of several dive sites in Jagna. All these dive sites are rarely visited, so they are pristine and undamaged. They have different conditions and characters, which means that some spots require a higher level of scuba diving experience and skill. Be sure to tell your scuba instructor/Divemaster your skill level.

3. All dive sites in Jagna can be accessed via shore entry. Because the highway is right alongside the coastline, a Drift Divers multicab will take you from one dive site to another. Of course, you can opt for a boat dive, and that will entail an extra expense for the boat rental.

4. Establish neutral buoyancy as soon as you descend to avoid touching the seabed.

5. The black corals rest at more than 100 feet. Do not dive down those depths without the supervision of your scuba instructor/Divemaster, especially if diving at such depths is prohibited by the terms and conditions of your license.

6. The dive shop will take care of your scuba equipment, so you don’t have to worry if you are not bringing your own set. Pack light but do bring the following:

  • extra water ( at least 2 liters per person)
  • swimwear
  • aqua shoes or slippers
  • hat
  • sarong or towel
  • snacks or packed meals
  • personal medication and toiletries
  • waterproof camera
  • mask and snorkel (for snorkelers)

5. Be a safe and responsible diver. Always observe the Leave No Trace principle. Never touch, disturb, tease, or collect marine wildlife. Remember we are in a protected area and an alien world that demands respect.

  1. Whoa! Such great pics!

    I’ve always been wanting to try scuba diving ever since I tried snorkeling once.

    • Hi Warjie,

      Sure! Scuba diving is absolutely awesome.

      We recommend you enroll in a DSD (Discover Scuba Diving) session first. This will let you experience scuba diving first-hand, which will help you decide if diving is really for you. If you love the experience and decide to pursue the hobby/sport/activity, then you can go for Open Water certification. πŸ™‚

  2. Nindota diri Sir! Glad we still have well preserved places like this.

  3. Waaa ganda. Just recently I was thinking of going on an intro to diving.

  4. Nice to know that there are people who care about these underwater treasures. How I wish I could dive too. I panic easily when my feet can’t reach the sea bed. πŸ™‚

    • Hi When In My Journeys,

      The ocean is vital in the planet’s survival. That’s why we should take very good care of it.

      Oh, you can definitely dive. It’s frightening at first, but once you go under the water’s surface, you’ll enjoy the experience of “flying” around the corals and swimming/breathing like a fish. In fact, we had a friend who suffers from aquaphobia. Scuba diving “cured” her. πŸ™‚

      • Thank you for the encouragement. Next project pag-uwi. πŸ™‚

      • We suggest you go for a DSD (Discover Scuba Diving) session first. This will help you decide if scuba diving is for you before you go for open water certification. Certification rates are generally expensive, so the DSD helps you make a decision before you invest a large sum of money.

  5. That looks like such an amazing diving adventure!!! Didn’t know there were different types of coral!!! Just wish I could swim so I could do all these fun water activities as well.

  6. Ang ganda ng white coral! ^_^ But wait, technically, eto rin ba yung “black coral?” O yung black coral ba yung black na kumpol-kumpol – the photo that follows the white coral?

    • Hi Claire,

      Yun talaga is black coral. It’s named after its black branch-like skeleton. Yung white is yung feathery polyps nya which are shaved off when harvested. πŸ™‚

      Yung mga kumpol-kumpol ay crinoids and pearl oysters.

      The black corals look like ghosts in the deep. πŸ™‚

  7. seems thrilling! I’d love to try diving once…but I am kinda scared! πŸ™‚

    • Hi Monika,

      Don’t be scared. πŸ™‚ Just like anything else, diving is safe as long as you follow your instructor/divemaster and you don’t exceed your limitations.

      The world under the sea is truly amazing!

  8. Looks like a fantastic dive! The water is beautiful!

  9. The Cantagay Marine Sanctuary looks like a stunning location. You captured so many beautiful images, so much colour.

    • Hi Only By Land,

      Thank you! Yes, it is one of the most diverse dive sites we’ve ever visited. A huge part of that reason is that Jagna has never been considered as a diving destination. Thus, the reefs under its waters are totally pristine. πŸ™‚

  10. Hi! I’m currently doing a marine biodiversity project which would require me to learn scuba diving (which I’ve been planning to for a long time btw). And since I’m from Jagna I’m thinking of getting my license at drift divers. However I really need to make sure that the instructor knows his job well (there are instructors kasi esp in touristy areas na “magmantinir” lang sa students) Would you recommend the instructor so I’d learn everything I have to learn about scuba diving? Thankss πŸ™‚

    • Hi Dina,

      Oh, yes, we can confidently recommend Jason. He’s really good and professional. And considering that Jagna does not have touristy dive sites, rest assured that they won’t “mantinir.” Hehehe! πŸ™‚

  11. Thank you for sharing this! This looked like an incredible adventure. That starfish you found was huge! The black coral was so pretty as well.

  12. WoW! Diving must me such a beautiful experience! I never did, just snorkelling but very fascinated by pics and descriptions of underwater world

  13. This place looks like a divers paradise. Thanks for informative article and great tips. I love your pictures.

  14. This sounds like a truly epic trip! Your photos are amazing and really paint a picture of all the amazing things you saw. It is so true that to see such rare things in nature is a gift and a privilege. Excellent article.

  15. What a truly amazing adventure! Life underwater is simply mystical and magical to say the least. Love your captures. Your journey actually gave a glimpse of the wonders the seas behold πŸ™‚

    • Hi Quirky Wanderer,

      The realm under the waves is truly incredible. We can see more creatures within 5 minutes of our dive than within 5 hours on a mountain trek. It just shows that we know so little about our world. πŸ™‚

  16. I spent two months in Panglao, Bohol, but I can’t recognize this place. In which part of the island is it?

  17. […] wonders are found beneath the waves such as Balicasag Island,Β  Arco Point, or even the distant Cantagay Marine Sanctuary. Hover over rich coral gardens, swim around with schools of vibrant fish, and immerse yourself in […]
