filter-feeders, grazers (herbivores), and carnivores; includes ectotherms (most fish, reptiles)

and endotherms (birds, marine mammals); oxygen uptake by gills (fish) and lungs (reptiles,

birds, mammals)

Anything in the Order Teuthida is considered a "squid". I would need to know the common name of the type of squid in question to answer further.

Kingdom: Animalia

Phylum: Mollusca

Class: Cephalopodo

Superclass: Decapodiformes

Order: Teuthida

Answer 3

sea animals.
