Biology     Glossary (e.g. epibenthic)

Littoral. On muddy bottom (Ref. 2082). Inhabits areas with low light levels (Ref. 106818). Associated with coralline bottoms ( Ref. 275). Capable of various color patterns, skin textures and body postures (Ref. 106818). Octopods are carnivores, preying mainly on crustaceans, fish and shelled molluscs (Ref. 96968). Members of the class Cephalopoda are gonochoric. Male and female adults usually die shortly after spawning and brooding, respectively. Mating behavior: Males perform various displays to attract potential females for copulation. During copulation, male grasp the female and inserts the hectocotylus into the female's mantle cavity where fertilization usually occurs. Life cycle: Embryos hatch into planktonic stage and live for some time before they grow larger and take up a benthic existence as adults (Ref. 833).
