Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 22.0 cm TL male/unsexed; (Ref. 96968)
Mantle length is 5.7 cm. This species is extremely venomous, tetrodotoxin venom produced in the salivary glands has potential to cause human deaths (Ref. 96968). It lives on intertidal and shallow subtidal reefs, seagrass meadows, and rubble areas. It emerges at night and forages for small crustaceans and fishes. Hatchlings are benthic (Ref. 96968).
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.
