Answer 1

Answer

Echinodermata is the Phylum in which Excreatory System is absent.

Excretion Process

Brittle stars, though, do not require an anus, and excrete through their mouths.

The waste comes out of the tube feet and the skill gills on the body.

The waste contains nitrogen in the form of ammonia.
