Finding Triton Trumpet!

This is exactly similar to what we found in the reef.

My dives during the CCC expedition led me to surprising encounters with marine critters, especially that their field base is nestled within Sogod Bay which is just one of the richest marine environment in the Philippines. We were having our second survey dive of the day doing outward for the fish survey, it was in pretty normal conditions, no current and animals were contentedly calm. I was scouring my side for the target species and unexpectedly this large shell came into view, I tried to come near but getting conscious that invertebrates was not our aim for the descent, time is always precious during survey dives! But the sighting was too rare to ignore, I tried to get Manon’s (our Project Scientist) attention – she was too absorbed as she was leading our mission. I pointed it out and she was surprised too! The intricate pattern of the its shell was just beautiful. We both came nearer and she signaled to record the sighting. That was my first encounter of a giant Triton in its habitat surrounded with other animals and I was wondering of its contribution to the marine ecosystem.

Here are are few facts I found at about the specie:

  1. This invertebrate is an active predator and is known to aggressively chase its prey, which it detects through its excellent sense of smell.
  2. The giant Triton is known for relatively high speeds, especially for a snail.
  3. They feed on other snails and sea stars, most notably the crown of thorns starfish (COTS), Triton is the only natural predators of this destructive starfish.
  4. The specie was considered extremely important to reef health and is given legal protection particularly in Australia.
  5. The giant Triton reproduces through internal fertilization, and the female lays her sticky eggs on the sand, where they quickly become covered with sand and other material, protecting them from potential predators.

Unfortunately, because of its valuable and attractive shell it is collected at many places around the world, they are often sold in shops or markets in popular tourism destinations in the tropics such here in Philippines.  Gladly, that night during dinner as we were discussing the day’s activities, the giant Triton was nominated as critter of the day and was voted by majority!

NB.    The giant Triton was sighted in Nueva Estrella Norte, a fishing community in Pintuyan, Southern Leyte where a marine protected area (MPA) was just established.

A Nudibranch to Know

This slideshow requires JavaScript.

Nudibranch (Nudibranchia) or simply called nudi in diving community are wonderful creatures, with odd shapes and vibrant colors one can’t miss them as it crawls on soft or hard corals among the reefs. They are lovely to behold and if you are sensitive on micro and subtle critters, these animals are exceptional.

Here are few facts I gathered about this lovely animal:

  • There are over 3000 identified species of nudi, it would take too wide and long to encounter them all
  • They are color blind or generally have poor vision and can only distinguish dark or light lumination
  • Nudis are hermaphroditic, which means capacitated with both male & female reproductive organs. Being solitary in nature, it needs to maximize their mating ability for reproduction
  • It has very short life span, it can only live not more than one year so there is no chance to encounter the same nudi in the next dive
  • They got their colors from their food, it has the ability to absorb and incorporate the tint & shade of their prey into their tissues such as anemones or sponges
  • Generally, it’s not for human consumption – often referred to as “butterfly of the ocean” due to vivid vibrant color and their intense toxicity – generally their loud color is a warning sign!

I love nudis and my dive won’t be complete if I don’t find one, I would conclude that the particular reef lacks the necessary as habitat for the critters and so not healthy. And I would reflect that perhaps I went too fast not to notice if there was one.  With more than 3000 species, one can imagine how vast and mysterious our ocean can be!

Few Facts on Barracudas

Not in their “alone time”, this group of adults are probably hunting for food.

Barracudas are mainly famous and are labeled as deadly sea creatures.  Recently, I had close encounter with a small school of them in the depths south of Panay Island. It was intriguing, as they didn’t quickly disappear from sight.  Compared when I first saw them just few months when I become a certified diver.  I watched in awe just few meters from me, the silvery group swimming coyly among themselves. It was a rare encounter!

These cold-blooded fish have not only swum the Earth’s oceans for the last 50 million years, they’ve also played a leading role in countless horror films. However, the barracuda doesn’t exactly live his life to terrorize swimmers; these scaly predators prefer to spend their days hunting fish, not humans!

Here are few facts on this dominant fish worthy to note:

• Barracudas vary in size, depending on the species. Largest species of barracuda can reach 6 feet in length and weigh up to 103 pounds.
• Upper part of the body is covered with scales that can be black, brown, grey or blue in color. Belly is always white. Irregular dark spots are located on both sides of the body.
• Barracuda has elongated body with pointed head. It has two dorsal fins and tail fin shaped like a fork.
• Barracuda has very sharp, dagger-like teeth which prevent slipping of the prey from the mouth.
• Barracuda’s diet consists of different types of fish: groupers, anchovies, mullets, snappers… Besides fish, barracuda sometimes eats squids and crustaceans.
• Shiny objects attract barracuda’s attention. Because of that, barracuda usually hunts fish with golden or silver scales.
• Barracuda is known as dangerous fish that can attack divers without any obvious reason.
• Barracuda can act as an ambush predator that attacks using the factor of surprise. When there is no place to hide, barracuda will chase its prey actively.
• Barracuda is nocturnal animal (active during the night).
• Barracuda can swim at the speed of 25 miles per hour. This feature is useful both for hunting and for escape from predators.
• Even though barracuda is one of the greatest predators in the sea, it can be prey of some large marine animals. Biggest enemies of barracuda are killer whales and sharks.
• Barracuda prefers solitary life, but it sometimes gathers in groups called “schools”. Life in a group provides safety and facilitates hunting (group of barracuda hunts cooperatively).
• Mating season of barracudas takes place in the spring. Males and females release eggs and sperm cells in the water where they will combine to form fertilized eggs. Females produce and release more than 1000 eggs but only few eggs will manage to survive until the adulthood.
• Barracuda’s age can be determined by counting the rings on the scales and on the otolith (structure in the inner ear). Number of rings matches the age of the fish.
• Barracuda can survive from 10 to 15 years in the wild.

Gorgonian Rider

Gorgonian Rider

Bargibanti pygmy seahorse (Hippocampus bargibanti) is a minute critter normally hosted by gorgonians, it was my first sighting while diving in Blue Hole of Romblon. It is hardly seen unless its host is examined closely, using magnifying glass could be better. Our DM was so keen on macro and it was fortunate we found one during the dive. This pygmy seahorse is well camouflaged, being extremely difficult to spot amongst the gorgonian coral it inhabits.

Large bulbous tubercles cover its body and match the colour and shape of the polyps of its host species of gorgonian coral, while its body matches the gorgonian stem. It is not known whether individuals can change color if they change hosts, although the ability to change color according to their surroundings does exist in some other seahorse species. This is also one of the smallest seahorse species in the world, typically measuring less than 2 centimeters (0.79 in) in height.
