Question

State the connecting links between Peripatus with Annelida and Arthropoda.

Answer 1

The living animals which posses some characters of two different groups of animal are called connecting link. Peripatus is a primitive arthropod having jointed paired legs, compound eyes and tracheas like other arthropods but also displays certain annelidan characteristics, such as worm-like segmented body, non-chitinous cuticle and segmental nephridia. Thus, it forms a connecting link between Annelida and Arthropoda.
