There is no such thing as a cuddlefish. It is called a "cuttlefish", and it is a large mollusc that is related to the squid and octopus.
cuddlefish are part of the food chain and when the food chain is messed up it ruins the eco system.
Cuttlefish are carnivorous and mainly feed on small fish, crabs, shrimp, and other crustaceans. They are skilled hunters, using their tentacles to catch and subdue their prey before eating them. Cuttlefish may also consume small mollusks and other marine invertebrates.

Magellanic Penguins eat small fish and cuddlefish. Because they have to swim out far, they are being damaged by currents and pollution, making them an endangered species.
It looks like part octopus and part squid. It's a strange animal, and some species of it can actually change color. They don't glide against the sand, they glide on their sides without the bottom of the sea to support them
