Summary Introduction
Introduction: The coelomate (main body cavity) phyla are divided into two distinct categories: Protostomes and Deuterostomes. The members of phylum annelida are considered as members of Lophotrochozoa (clade of the protostome animals) that also includes molluscs and

Students have asked these similar questions
compare cnidarians to sponges and to the clade containing flatworms, mollusks, and annelids. What features are similar among these groups? What features are different?
If nematodes are the most numerous animals, the Arthropoda, including insects, are the most diverse, accounting for more than half of all known animal species. What features have led to the remarkable evolutionary success of this branch?
Which of the following statements is true?
--Sea stars are dioecious possess dermal branchiae and they have two stomachs
--Actinoptergians are fleshy/lobe finned with cycloid scales and a swim bladder
--Ophiuroidea have bilateral larvae, and Aristotle's lantern and five arms
--Sand dollars are echinoderms with long spines, gills, and pentaradial larvae
--Sharks have an operculum, cosmoid scales and eyelids

Some Platyhelminthes have a coelom, but others do not and it is difficult to conclude anything about its evolution within the clade. c. Platyhelminthes originated from ancestors with a coelom and have retained it to the present time. d. Modern Platyhelminthes do not have a coelom but did originate from an ancestor that had one. e.
