59. one of the following is considered as a living and connecting link between annelida and arthropoda: a.peripatus b.balanoglossus c.sphenodon d.limulus
Correct option is A) 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’.
