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.

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.

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

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 female reef octopus decreases the food amount it eats by almost 50% about two weeks before laying eggs.

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.
