Question

Ichthyophis belongs to which class?
A Reptilia
B Amphibian
C Aves
D Pisces

Answer 1

Hint Ichthyophis is a caecilian genus that can be found in Southeast Asia, the Philippines, and the western Indo-Australian Archipelago. Three species can be found in Sri Lanka. All of them can be found in practically any habitat, but they favour damp ones.

Complete step by step answer:
The Ceylon caecilian, also known as the common yellow-banded caecilian, is an indigenous Sri Lankan caecilian of the family Ichthyophiidae. Moist tropical and subtropical forests, as well as grasslands, are its natural habitats.
Amphibia includes Ichthyophis. Caecilians belong to the genus Ichthyophis. These organisms resemble long snakes. Amphibians are vertebrates with cold blood. They have a backbone and rely on external measures to regulate their body temperature, like lying in the sun. Amphibians spend part of their lives in the water and part on land.
They have permeable skin that allows gases and certain molecules to pass through, as well as gills for a portion of their existence.

As a result, option A is the proper response.

Additional information
The following are the characteristics of Ichthyophis:
-These limbless amphibians prefer damp soil and rely on borrowing to survive.
-It is extended and can reach a length of up to 30 cm.
-Dark brown or blue black with yellow streaks running along the edges.
-Coecilla is a type of skin with transverse grooves, slime glands, and squirt glands that produce unpleasant fluid.
-There are no limbs or girdles. The tail is either short or non-existent. The eye is quite small.
Compact skull with bony vertebrae as a roof.

Note: The caecilians are the first terrestrial animals and the oldest of the amphibians, making them immensely important in evolutionary terms. They serve as a link between land and sea species. There is no evolutionary evidence available because these creatures do not have a fossil record.
