Coral, jellyfish, and aneomes are hollow bodied animals
The Spiny skin sea-animals also known as Echinoderms consist of about 6000 species. They are commonly grouped together as starfish and sea urchins.
Spiny-skinned animals, such as sea urchins and starfish, have a hard exoskeleton made of calcium carbonate plates called ossicles. They have tube feet for movement and feeding, and their skin is covered in spines or bumps for protection. These animals typically have a water vascular system that helps with movement and feeding.
Some species of crayfish, such as the spiny lobster, are saltwater animals, while other species, such as the kabby or koura, are freshwater animals. It all depends on which species of crayfish you are referring to.
Some animals that have thorns include the porcupine, certain species of sea urchins, and spiny anteaters. These thorns are often used for defense against predators or to help with camouflage.

The scientific name for spiny-skinned animals, such as sea urchins and sea stars, is Echinodermata. This phylum includes marine organisms with a calcareous endoskeleton covered by spines or plates.
An echinoderm is a spiny-skinned organism like a starfish. Leeches are soft bodied organisms, so they can't be echinoderms.
