Endoskeleton of echinoderms-analogous structures
How can endoskeleton of echinoderms be typified in comparison to analogous structures present in the vertebrates, in arthropods and in molluscs?
Expert
The echinoderm skeleton is inner, that is, it is the endoskeleton. It is made of calcium carbonate (or calcareous). Vertebrates also have inner skeleton made of cartilages and bones. Arthropods have an outer carapace made of chitin, chitinous exoskeleton. Some molluscs present calcareous shell which works as an exoskeleton.
