Question

The respiratory organ of peripatus is :

• A. Skin
• B. Book lungs
• C. Trachea
• D. Gills

Answer 1

Answer:

C. Trachea

The respiratory organ of the Peripatus is the trachea.

Peripatus, also known as velvet worms, are unique organisms that belong to the phylum Onychophora. Despite their worm-like appearance, they are evolutionarily closer to arthropods, and their respiratory system is a key characteristic that supports this classification.

Unlike the gills or skin used for respiration in many other invertebrates, Peripatus has a system of fine, unbranched tubes called tracheae. These tubes open to the outside through tiny pores called stigmata and branch throughout the body, delivering oxygen directly to the tissues. This is a very efficient system for gas exchange, similar to that found in insects and other terrestrial arthropods.
