Which one forms a connecting link between annelida and arthropoda?
Peripatus belong to the phylum onychophorans. The eyes of onychophorans are similar in structure to those of some true, or segmented, worms (annelid). They consist of only two families, Peripatidae and Peripatopsidae. In evolutionary development, they are considered to lie between annelid worms and arthropods (e.g., insects and crustaceans).
So, the correct answer is ‘Peripatus’.
