Question

Salient features of peripatus deep explination

Answer 1

Peripatus is a terrestrial animal found living in moist places, in crevices of rocks, under bark, stones, logs and beneath fallen leaves and other dark and damp places or along stream banks. It is generally confined to humid habitats. It is nocturnal in nature and predaceous and carnivorous in feeding habit. Most species of Peripatus are predaceous and feed on small invertebrates, such as snails, insects and worms. A number of species display a particular preference for termites. Most species of Peripatus are viviparous and a single large female may produce 30 or 40 young ones in a year. The head of Peripatus bears a pair of eyes, a pair of antennae, a pair of jaws or mandibles, and a pair of oral papillae. Peripatus is predaceous and carnivorous and its food comprises small invertebrates, such as snails, insects and worms. The circulatory system consists of a single mid-dorsal tube, the heart placed on the dorsal surface of the gut. The heart is tubular and contractile, lies within the pericardial sinus. It is provided with a pair of lateral ostia in each segment. The heart extends from the segment bearing first pair of legs to the segment immediately before last. The respiratory system consists of air tubes called tracheae or tracheal tubes. The tracheae are delicate, un-branched or rarely branched tubes. They are lined by a thin chitinous layer exhibiting faint transverse striations. The tracheae extend throughout the body and communicate to outside through minute spiracles. The excretory organs are nephridia. The nephridia are segmentally arranged pairs of coiled tubes. Each segment contains a single pair of nephridia located in the ventrolateral sinuses. The nephridia correspond to the pairs of legs. A typical nephridium consists of a long ciliated funnel, a coiled duct and a contractile bladder called vesicle. The sexes are always separate and the cavities of the reproductive organs are coelomic. The males are usually smaller than females.

Answer 2

Answer:

Peripatus:

• An arthropod is a connecting link between annelida and arthropoda.
• It's arthropod characters include haemocoel, tracheae as respiratory organs and tubular heart with Ostia.
• The annelid characters exhibited are the worm like body, structure of the eyes, unjointed legs, presence of segmental nephridia, soft cuticle and continuous muscle layer in the body wall.
