Caribbean Reef Octopus: 15 Facts You Won’t Believe!

Interesting Caribbean reef octopus facts that will make you love them more.

These vibrantly colored octopuses hold the title of being the smartest of all invertebrates. They are unique in the sense that they can change the color and texture of their body to blend into their surroundings. This not only helps them to evade their predators but also to search for their prey sneakily. Thankfully, they are not a threatened species as of now, even though, humans have been hunting them for food since forever. However, experts have stated a concern as their existence is directly tied to the existence of coral reefs and as the latter continues to be endangered, the existence of this beautiful octopus can become questionable too. Any living organism plays a direct part in the well-being of others, and if the existence of one is threatened, others might have to face the consequences presented by the ecosystem as well. This is why it is important to keep their numbers stable before it is too late. Read on to learn more interesting facts about this marine creature.

How do they reproduce?

They are monogamous and only mate once in their lives. These marine octopuses have two known ways of mating. Either the male octopuses mate with the female and release the sperm inside their body to fertilize the eggs, or they give their hectocotylus to the females and the females store it inside their mantle until the eggs are ready to be fertilized and then extract the sperm from their mantle. These octopuses lay about 300-500 eggs per pregnancy. The male octopuses usually die a few months after they give their hectocotylus to the female, while the female generally dies after laying eggs and making sure that they are in a safe place until the eggs hatch.

This reef octopus is known to have eight long legs, or tentacles, of different sizes, and a mantle that is large with dark-colored eyes. The longest pair of legs, namely the second and the third one is known for growing almost five times bigger than the size of the mantle.

These blue-green predators are also known to use sound to locate their prey.

The octopus briareus is known to be a nocturnal species that searches for its food during the night. This helps them to stay away from their predators, and also helps them in hunting for their food. Their primary food habit consists of shrimp, spiny lobsters, crabs, and small fish. However, Caribbean reef octopuses have been known to indulge in cannibalism as well, that is, they are known to eat members of their own species. Their teeth and suckers are divided into seven and two rows respectively which helps them to catch their prey. These marine creatures are known to often surprise their prey by launching themselves over coral reefs, while sometimes this predator is known to stalk its prey from behind and wrap its front tentacles around the prey to capture it. The amount of food they take in completely depends on the sources of food available as well as on the temperature of the water. The female reef octopus decreases the food amount it eats by almost 50% about two weeks before laying eggs.

Are they poisonous?

However, this predator is the smartest of all invertebrates in the ocean ecology, so, they are more than equipped to fight off potential threats. They are known to discharge a kind of ink cloud as a deterrent to their predators which tastes extremely bad and is enough to throw the predator off course for a short time.

Would they make a good pet?

Octopuses in general make appealing pets, and this reef octopus is no different. With their vibrant appearance and beautiful tentacles, they can add glamour to your aquarium. You should only keep in mind that the tank size should be around 50-75 gallons and the temperature should be around 72°-78° F (22-25 C). They also have a knack for escaping so a solid roof would be helpful. Feeding them is also quite easy as even the larvae are pretty well developed and can consume crustaceans from the beginning. Other than that, you can decorate the tank with coral reefs to make them more comfortable in their surroundings.
