Hints & Solution

(b) Peripatus is a genus of Onychophora (Velvet worms). It is said to be a living fossil because it has been unchanged for approximately 570 million years. Peripatus is a nocturnal carnivore. Peripatus is a connecting link between Annelida and Arthropoda. It feeds by trapping its prey (mostly small insects) in a white, sticky fluid it ejects from two antennae near its head. The fluid hardens on contact with the air and then the prey becomes immoblized.
