Abstract: The egg masses of big fin squid, Sepioteuthis lessoniana were collected from the wild and their intercapsular embryonic development was studied. The average incubation period of the egg varied between 18-20 days. The cleavage started on the first day and the mantle developed between third and fifth day. The yolk started decreasing eighth day onwards. The tentacles with the sucker primordia on the tip were prominent from tenth day. The yolk totally reduced between thirteenth and seventeenth day and the paralarvae hatched out on eighteenth day.The developmental stages of the embryo inside the capsules during the incubation period is understood.
