Like some modern squid, belemnite arms carried a series of small hooks for grabbing prey.
Belemnites were efficient carnivores that caught small fish and other marine animals with their arms and ate them with their beak-like jaws.

In turn, belemnites appear to have formed part of the diet of marine reptiles such as Ichthyosaurs, whose fossilized stomachs frequently contain hooks from the arms of cephalopods.

Belemnites swam in near-shore to mid-shelf oceans.
