A cuttlefish is not a fish at all but a marine invertebrate. Cuttlefish are molluscs in the class cephalopoda along with octopi and squid. Molluscs also include bivalves (clams, oysters and mussels) and gastropods (snails and slugs).
No, cuttlefish are not crustaceans. They are a type of marine mollusk, related to squids and octopuses. Crustaceans are a separate group of arthropods that include animals like crabs, lobsters, and shrimp.
No. Squids eat other marine animals; therefore being a carnivore.
No. Octopi and cuttlefish are related, but they are not the same. Both belong to a class of marine invertebrates cephalopods, which also includes squid. One key difference is that squid and cuttlefish each have eight arms plus two tentacles while an octopus simply has eight arms.
Cuttlefish can vary in size depending on the species, but they typically range from 15-25 centimeters (6-10 inches) in length. The largest species, the giant cuttlefish, can grow up to 50-60 centimeters (20-24 inches) long.
Chromatophores They are most notable in brightly colored squid, cuttlefish and octopuses. Each chromatophore unit is composed of a single chromatophore cell and numerous muscle, nerve, glial and sheath cells. Inside the chromatophore cell, pigment granules are enclosed in an elastic sac, called the cytoelastic sacculus. To change color the animal distorts the sacculus form or size by muscular contraction, changing its translucency, reflectivity or opacity. This differs from the mechanism used in fish, amphibians and reptiles, in that the shape of the sacculus is being changed rather than a translocation of pigment vesicles within the cell. However a similar effect is achieved.
The term "true fish" would normally be applied to bony fish, technically known as teleosts. The cuttlefish is not a teleost, it is a cephalopod, which is a type of mollusc.
Yes, the cuttlefish.
cuttlefish. and alot of other fish that are smaller than it.
Yes, tuna fish do eat cuttlefish.
The mouth of cuttlefish is armed with a sort of parrot-like beak. It is surrounded by eight arms and two longer tentacles, the later of which are used for ensnaring the cuttlefish's prey and in the cuttlefish's mating ritual.
Yes. Cuttlefish prey on small fish and marine invertebrates.
Cuttlefish are voracious predators that are thought to be able to work in groups to hunt. They feed on fish, mollusks and arthropods. Phytoplankton is not all that hard to hunt. You just need something to filter it out.
The cuttlefish eats tiny fishes, and squids.

cuttle fish is not a vertabrate. its an invertebrate.
Cuttlefish is not a fish! It has no vertebrae and belongs to the class cephalopoda along with octopi and squid. As molluscs, they are more closely related to slugs and snails.
