Question

Which one of the following arthropods share some character with annelids?
A. Limulus
B. Peripatus
C. Boophilus
D. Scolopendrium

Answer 1

Hint: The animal sharing character with annelids being arthropods has a soft, elongated body packed with thin cuticles, is soft with segments, and has a velvety feel. It also has appendages that are paired. It exhibits the attributes of both arthropods and annelids.

Complete answer: Generally, invertebrates are soft-bodied creatures that fail to develop a rigid internal skeleton for muscle attachment, but also have a stiff outer skeleton. Invertebrates belong to more than 90 percent of all living animal groups.
-Peripatus relates to the Onychophora phylum. Like other arthropods, it has joined paired legs, compound eyes, and tracheas and moreover exhibits some features of Annelida, such as worm-like segmented body, non-chitinous cuticle, and segmental nephridia. Some structures which are close to annelids and some other structures found in arthropods are seen in the body of Peripatus. They are also considered to be the linking connection between Annelids and Arthropods.
-Limulus and Scolopendrium both belongs to the Phylum Arthropoda.
-Boophilus is the first aspartic proteinase characterized as part of the yolk deaIt was the first aspartic proteinase characterized as part of an arthropod egg's yolk degrading enzymatic repertoire. So, it is an arthropod.
Hence, the correct option is B- Peripatus.

Note: The phylum Annelida has similar characteristics to arthropods. Both arthropods and annelids feature segmented bodies, and there are a set of appendages around each segment for certain members of the annelid. Like a tubular, dorsal heart and similar nervous system, both groups exhibit similar body architecture.
