Most Interesting Marine Life Found in the Philippines
Dugong (Sea Cow)
Being a herbivorous marine mammal, dugongs feed on seagrass – from the leaves down to the roots. They are commonly found in shallow water with high concentration of seagrass, although they are rarely found in groups because there’s usually not enough food to support large population. Referred to as “lady of the sea”, dugongs are approximately 3 meters in length. Their number in the country has significantly decreased and is one of the marine animals with threatened population worldwide. Dugong is the first marine mammal placed under protection in the Philippines.
Also called humphead wrasse and locally called mameng, this marine animal is usually found on coral reefs. They typically measure approximately 1 meter from tip to tail but there are those that can grow up to 2 meters in length. They are notable for the hump on their foreheads, hence the other name. They are also noted for their thick lips and their color which vary from blue-green to green and purplish-blue. Their population is declining due to reasons such as illegal and overfishing, habitat loss, and poor management. They are listed as endangered species and are being conserved and protected.
Pacific Bluefin Tuna
The bluefin tuna is considered as a luxury fish and is one of the world’s most expensive tuna. But because of their commercial value and high market demand, their population greatly declined and is now considered as a threatened species.
Rare or Endangered Marine Life Found in the Philippines
Out of 7 sea turtles in the world, five of it can be found in the Philippines – the critically endangered hawksbill, the endangered green turtle, and olive ridley, loggerhead, and leatherback as vulnerable. Unlike its freshwater cousins, sea turtles cannot retract their head, legs, and arms into their shell for protection but this body structure makes swimming easy. And because they have lungs and breathe air, they need to surface for air at regular intervals. Places to visit for turtles sighting include Apo Island, Apo Reef, Helicopter Island (El Nido), Pescador Island (Cebu), Balicasag Island, and Mantigue Island (Camiguin).
Giant clams, particularly the genus Tridacna gigas is one of the most endangered clam species found in the country. These clams can weigh over 200 kilograms and can measure as much as 47 inches. They have become endangered because of the high demand not just in Southeast Asia but also in France and several Pacific Islands where they are considered as delicacy. Giant clams are called taklobo in the Philippines
Fin whale is the second largest species in the world with the largest measuring up to 27 meters. They are fast and strong swimmers with the average speed between 37 km/h to 41 km/h. Though they can live close to 100 years, they have become endangered due to excessive whaling in the 19th and 20th century.
Dangerous Marine Life Found in the Philippines
A popular aquarium fish, the lionfish is interesting to look at because of their colors, fins, and rays, humans should be wary when interacting with them because their fins contain venom which can cause extreme pain, vomiting, fever, difficulty in breathing, convulsions, heartburn, and diarrhea among others.
Heard about a local celebrity who almost lost her life to box jellyfish? Or that 7-year old Filipino-Italian who died after being stung by this highly dangerous marine life? There’s reason they are considered the “world’s most venomous creature”. The venom is so potent that it can cause death within 2 to 5 minutes especially without immediate treatment.
This species can grow up to 30 inches and is recognized as the largest species of triggerfish in its range hence also called giant triggerfish. Females may attack divers when the nest is threatened especially during reproduction season so care must be taken when around them.
Banded Sea Snake
When you see this marine life with distinctive black stripes and yellow snout, you better be cautious and avoid doing something that could threaten them for their venom can cause your respiratory system to fail.
While they look interesting, you do not want to mess with them because the blue-ringed octopus is recognized as one of the world’s most venomous marine animals. They may be small at 12 to 20 cm. but their venom may cause paralysis, respiratory failure, coma, or even death if not treated immediately. They feed on small crabs and shrimps, and inhabits tide pools and coral reefs.
Over 100 New Species of Marine Life Recently Discovered in the Philippines
Verde Island Passage is a portion in Coral Triangle with the richest marine biodiversity. As such, researchers keep on exploring the area in the hopes of discovering something new. Their exploration not so long ago gave them the opportunity to reach unexplored areas – some with depths between 150 to 500 feet. This resulted to the discovery of 100 new marine life.
The skeleton of a heart urchin was first discovered in 2014 but this expedition gave way to the discovery of a live heart urchin for the first time. The heart urchin has marvelous pinkish-white spines as fine as the hair.
More than 40 varieties of nudibranchs were discovered during this expedition. One is a bright purple-colored one with orange margin and a white-colored one with bright yellow spots.
Protect & Preserve the Philippine Seas
The Philippines doesn’t only have beautiful beaches with powdery white-sand and pristine waters. What lies in the depths of the seas are equally, if not more, interesting. The country has one of the richest marine biodiversity and home to various endangered species. Marine products are an important source of protein, too, and fishing is a main source of livelihood among several Filipinos.
Sadly, the condition of our seas in general is deteriorating. Overfishing and destructive fishing (using dynamite, cyanide, etc.) are two major factors causing the decline. Poorly-managed tourism as well as climate change make matters worse.
If not addressed properly and immediately, things will definitely not get any better and will only lead to the total destruction of the marine life in the Philippines. Presently, the government has laws and programs aiming to protect the country’s natural resources. Let’s just hope the laws are implemented strictly and everyone learns to cooperate.
Below are some of the things you can do to help conserve and protect the sea.
Minimize the use of plastic.
Many of our household stuff are made of plastic. Our foods are usually wrapped in plastic. While they may be useful at some point, plastic can be destructive especially if not disposed properly. Not only do they clog the waterways and cause floods, they can poison and choke animals to death too. Ditch your plastic bags in favor of reusable ones. If the use of plastic bag is really necessary, choose the biodegradable one. When shopping for groceries, bringing your own bag (and container for fish and meat) will lessen the use of plastic bags.
Choose reusable stuff such as food and water containers, and utensils. Using reusable stuff may take more effort but it’s definitely worth it. Plus it can save you money in the long run.
Go for sustainable seafood choices.
When dining out or buying fresh seafood, choose those that are sustainable and avoid buying overexploited species.
Use marine-friendly sunscreen.
Studies show that most sunscreen products contain chemicals that are toxic to the underwater inhabitants. Fortunately, there are now sunscreens that are marine-friendly.
Support groups and organizations protecting the seas.
Several groups and organizations are working hard to protect and conserve the seas. Technology makes it easier for people to find and join these groups. Joining one of these groups isn’t enough though. Being involved in the projects and activities definitely makes more impact.
Be an example.
Showing others what you do for the community isn’t necessarily bragging but can inspire others to do the same.
