The habitat of different squid species varies, some living in warmer, tropical, shallow sea waters while others in the cold depths of the oceans. Some squids thrive in the seas of the polar regions.
Carnivorous by nature, their diets mainly consist of fish and crustaceans like crabs. However, cannibalism has been observed in some species eating not only other squids but also members of their own species. Some squids eat up to 30% of their total biomass, with certain species even eating more.

Fast Facts. The females tend to be larger (body to 2.5 cm) than the males (body to 1.6cm). Pygmy squids are the smallest of all the Cephalopods. The order Idiosepida (and family Idiosepiidae) is represented by a single genus. Seven species have been described (five from the western Pacific Ocean and two from South Africa).
The pygmy squid paralyzes shrimp within one minute, using a cephalotoxin. The prey must be held in the right position otherwise it will not be paralyzed, and I. paradoxus must shift where it is grasping the prey. On occasion more than one pygmy squid will attack the same prey. Usually the first attacker will get the meal.
