<h2>Phylum Annelida</h2>

Explanation:

The given animal must be an Annelid.

Annelids are commonly called segmented worms. The characteristics features of annelid are:

Segmented bodies , each segment is called annuli.
Closed circulatory system.
Stiff appendages and flexible skin.
Eucoelomate i.e the presence of true coelom.
Nephridia as excretory organs.

Since the animal discovered by the marine biologist has a segmented body and true coelom, it is obviously categorized in Phylum Annelida.
