Question

Suppose you discover a new species of animal that does not have body segments, but is triploblastic, eucoelomate, and cephalized. Under the molecular phylogenetic scheme, you would allocate it to which phylum?

Answer 1

Mollusca

Step-by-step explanation:

A triploblastic, cephalized and eucoelomate organism but not segmented could belong to the phylum Mollusca. They are triploblastic, eucoelomates (with true coelom), and cephalized. The chordates have heteromeric segmentation while in molluscs none.
