Abstract

Cephalopods display some of the most complex behavioural adaptations amongst marine invertebrates, particularly concerning their mating behaviour. The reproductive features of the squids are unique. Sperm transfer is a complex process, with males transferring intricate spermatophores to females during copulation and the spermatophores everts as spermatangium by spermatophoric reaction. This in turn gets attached to the female body through distinct mechanisms. The squid spawning grounds of cephalopods, are generally identified based on the presence of egg masses and mated individuals. The Little Indian squid, Loliolus hardwickei (Gray, 1849) is known to inhabit estuarine and coastal waters to a maximum recorded depth of 30 m. They have a short life span of < 6 months. Nothing is known about the mating season of little Indian squid L. hardwickei and presumably the first record of a mated L. hardwickei from the southwest coast of India is reported below.
