A marine biologist dredges up a small animal from the bottom of the ocean. It is uniformly segmented, with short, stiff appendages and soft, flexible skin. It has a complete digestive system and a closed circulatory system, plus multiple true coeloms. Based on this, you determine that the animal must be a(n) . See Concept 33.3 (Page 701)

Explanation:

The given animal must be an Annelid.

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

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

c genetic engineering

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom
