What do octopuses eat?

Newly hatched octopuses will eat small foods such as copepods, larval crabs, and sea stars. Adult octopuses feed on crabs, clams, snails, small fishes, and even other octopuses. All species of octopus have venom of varying levels of toxicity, which they inject using a beak that is similar to a bird’s.

Though some can attack larger prey, like sharks. Octopuses typically drop down on their prey from above and, using powerful suctions that line their arms, pull the animal into their mouth.

Why does Octopus have 3 Hearts, 9 Brains, and Blue Blood?

Octopuses have 3 hearts because two pump blood to the gills and a larger heart circulates blood to the rest of the body.  

Octopuses have 9 brains because, in addition to the central brain, each of the 8 arms has a mini-brain that allows it to act independently. 

Octopuses have blue blood because they have adapted to cold, low-oxygen water by using hemocyanin, a copper-rich protein.

In short, octopuses eat crustaceans, mollusks, and fish which share their habitat. While not finicky, they can express favoritism for certain prey in times of abundance.
