The Caribbean Reef Octopus lives in warm waters around coral reef environments and grassy and rocky sea beds. There are more than 300 different species of octopus that have been identified. Considered the most intelligent of all invertebrates, the octopus is found in the tropical and temperate waters of the worlds oceans. They prey on crabs, crayfish, and mollusks, and will sometimes use their ink to disorient their victims before attacking. Its first line of defense is its ability to hide in plain sight. Using a network of pigment cells and specialized muscles in its skin, the octopus can almost instantaneously match the colors, patterns, and even textures of its surrounding. Predators such as sharks, eels, and dolphins swim by without even noticing it. When discovered, an octopus will release a cloud of black ink to obscure its attackers view, giving it time to swim away. The ink even contains a substance that weakens a predators’ sense of smell, making the fleeing octopus harder to track. Fast swimmers, they can jet forward expelling water through their mantles. And their bodies can squeeze into impossibly small cracks and crevices where predators can’t follow.
