Cuttlefish
Alternative names: Sepiida
Cuttlefish are marine animals that have an unique internal shell named the "cuttlebone". The cuttlefish is a master of camouflage thanks to its ability to mimic the shape and texture of objects around them.
During mating season, if a male isn't as big and as strong as other males, it will try to disguise itself as a female in order to swim past the other males and mate with the female.
Evenmore, Cuttlefish has an incredible ability to almost completely see behind themselves thanks to their W-shaped pupils and they can also see well in low light and can detect polarized light.
