Short description Morphology

Umbilicus filled in with concretion; flame-striped color pattern extending across nearly entire shell

Occurs on the continental shelf and slope. Prefers hard bottoms particularly coral reefs (Ref. 88739), on steep faces (Ref. 106682). Exhibits diel vertical migration. Broken shell washed up on beach (Ref. 88739).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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.
