(D) Aves
Ichthyophis Belongs to Class Amphibia: CSIR NET Solved Question Q86
Ichthyophis is a genus of caecilians classified under Class Amphibia. The correct answer to Q86 is (C) Amphibia.
Option Analysis
-
(A) Mammalia: Mammals feature hair-covered skin, mammary glands for milk production, and live birth in most cases. Ichthyophis lacks these traits, as it is egg-laying without fur or glands.
-
(B) Reptilia: Reptiles have dry, scaly skin, lay amniotic eggs on land, and are fully terrestrial or aquatic without dual life stages. Ichthyophis has moist skin and aquatic larvae, unlike reptiles.
-
(C) Amphibia: Amphibians show moist, glandular skin, dual life (aquatic larvae, terrestrial adults), and include orders like Apoda (caecilians). Ichthyophis fits as a limbless, burrowing caecilian in family Ichthyophiidae.
-
(D) Aves: Birds possess feathers, wings, beaks, and are warm-blooded fliers with hard-shelled eggs. Ichthyophis is worm-like without these avian features.
