starfish doesn't have any hard shell to protect itself but it does release poisonous stuffs
no because a starfish has a hard shell and can never die
No. A starfish has a hard shell and its inside is only organs. To be considered a vertebrate the starfish would need a spine and an internal skeleton (not to mention a head). They are, therefore, classified as invertebrates.
The difference is simply the animal inside. Hen eggs produce chickens if they are fertilized, and starfish eggs produce starfish. Also, starfish eggs do not have a hard shell - they are somewhat gelatinous.
A starfish feeds on a clam by first using its tube feet to pry open the clam's shell slightly. Once the shell is opened, the starfish extends its stomach through its mouth and into the clam's body, secreting digestive enzymes to break down the soft tissue. After digestion, the starfish retracts its stomach, absorbing the nutrients. This process allows the starfish to consume prey that is otherwise protected by a hard shell.
When a starfish pries open the shell of a clam or oyster, it uses its tube feet to exert pressure on the shell. The mollusk instinctively tries to close its shell to protect itself, but the starfish can exploit even a slight opening. Once the shell is slightly ajar, the starfish extends its stomach out of its body and into the clam or oyster, secreting enzymes to digest the soft tissue before absorbing the nutrients. This method allows the starfish to feed effectively despite the mollusk's resistance.
When starfish catch prey and get the shell cracked open they regergitate their stomach which releases enzymes to kill and liquify the prey. After it's liquified the starfish basically swallows its stomach along with its food.
well they are but they don't have a shell
Starfish eat clams by grasping and pulling on the clams shell until the clam can't hold it close any longer. Once the shell is opened far enough, the starfish begins to feed on the clam.
Yes, starfish do eat sea urchins. They wrap themselves around the sea urchin and evert their stomach against it to dissolve away the flesh and shell. Eventually when the flesh and shell is dissolved by the starfish stomach acids, the starfish eats the inside of the sea urchin.
A Starfish has a shell that looks like cuttlefish bone, but very delicate
They get hard and brittle when they dry out.
Starfish do not have fur. They actually have soft spines that cover their whole bodies. These are used for protection.
