Biology     Glossary (e.g. epibenthic)

Total length to 53 cm (Ref. 96968). Common in coastal Northeastern Brazil and its oceanic islands (Ref. 104094). Found on bedrock and gravel, regardless of the presence of algae (Ref. 96968). Also occurs on sand beds, rocky bottoms (Ref. 104094) and crevices on hard substrates (Ref. 104098). 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 (Ref. 833). Spawning occurs in deeper waters (Ref. 104886). 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).
