Question

"I have an animal in front of me that is asymmetrical, has no tissues layers and eats plankton. This animal is a member of which phylum?"

Answer 1

Animals with radial symmetry have no right or left sides, only a top or bottom; these species are usually marine organisms like jellyfish and corals.

Most animals are bilaterally symmetrical with a line of symmetry dividing their body into left and right sides along with a “head” and “tail” in addition to a top and bottom.

Only sponges (phylum Porifera) have asymmetrical body plans
