10. Reproduction
Sepia latimanus mates in
shallow water between January
and May. This species mates
head-to-head and the male
places spermatophores on the
female's buccal membrane near
her mouth. The eggs harden after
they are laid. Their eggs hatch in
38 to 40 days. During the
breeding season, males establish
a territory, defending a coral
head where females lay eggs
after mating(2).
11. Lay eggs in water until hitch is become out side
small animal like parent but small in size. After that
became adult.
