What are differences shrimp and starfish?
Crayfish have an external skeleton and starfish have an internal skeleton relying on a water vascular system for movement.
Is a starfish a hydro static skeleton or a exoskeleton?
A starfish has a hydrostatic skeleton, which means it relies on the pressure of its internal fluids to maintain its shape and support its body. This type of skeleton allows for flexibility and movement, enabling the starfish to navigate its environment. In contrast, an exoskeleton is a rigid external structure found in organisms like insects and crustaceans, which is not applicable to starfish.
What bony plates make up a starfishs skeleton?
The bony plates that make up a starfish's skeleton is the ossicles. They are found in not only starfish but sea cucumbers and sea urchins also.

What is the nature of the starfish skeleton?
Starfish's skeletons are much smaller and they are shaped like a star.Starfish are invertebrates, meaning that they do not have have backbones or the bones to which arms and legs are attached on the human skeleton.AnswerStarfish have hydrostatic endoskeletons made of hard, bumpy, spiny ossicles. They are invertebrates, meaning that they do not have a backbone or spinal cord. Their skeletons require water to function, hence the name hydrostatic. Humans have bones made of different materials, and they have joints, unlike starfish. STARFISH DO NOT HAVE EXOSKELETONS. They are Echinoderms, not Arthropods.
