Question

Explain how your chosen invertebrate fits into the cladogram of invertebrates.

Star Fish

Answer 1

A starfish fits into the cladogram because invertebrates are being with exoskeletons or no skeleton at all. It fits into the invertebrates part of the cladogram.

Answer 2

The starfish is an echinoderm, this group is closely related to sand dollars, and feather stars. The echinoderms don’t have a notochord, and they are not closely related to chordates, they have no backbone like all invertebrates, they have external skeletons of calcareous plates. They are multicellular and all the cells have different responsibilities to keep the animal alive.

For all this characters they fits into the cladogram of invertebrates.
