I know a segmented worm does.
Mollusks compose of the large phylum of invertebrate animals known as the Mollusca. Mollusks have a mantle, mollusks invertebrate. Arthropods have jointed appendages, arthropods have segmented bodies
Athropods. Certainly!
Yes these two share common ancestors.
Yes, molluscs fit into the group known as protostomes.
wat do all the worms have in common
lol, are you doing sections 1 and 2 for mollusks and segmented worms?
Mollusks and segmented worms have a one-way digestive system, a separate mouth and anus, and their larvae are very similar. This is the best evidence that they have a common ancestor.

Arthropods have the common characteristics of exoskeletons made of chitin, necessitating the further characteristics of segmented bodies and joint appendages. The phylum's name arthropoda comes from the greek meaning jointed legs or feet.
