Salamander is a member of 

  1. Aves

  2. Amphibia

  3. Mammalia

  4. Reptilia


Correct Option: B
Explanation:

The characteristics of salamanders are as followed:

  • They have soft, wet skin like a frog to adapt in a wet environment.
  • They lay spawns where the tadpoles will hatch like frogs.
  • Also, they have gills, lungs for respiration in water and land respectively.
  • These are main characteristics that Amphibians show. 

Aves are birds and salamanders aren't one of them. Salamanders lay eggs so they can't be grouped under Mammalia. Reptiles have no wet skins, respiration is through lungs(absence of gills).
So, the correct answer is 'Amphibia'.

Select the correct classification of Rana tigrina upto genus level.

  1. Chordata, Craniata, Amphibia, Gnathostomata, Rana

  2. Chordata, Craniata, Gnathostomata, Amphibia, Rana

  3. Chordata, Craniata, Gnathostomata, Craniata, tigrina

  4. Chordata, Craniata, Amphibia, Gnathostomata, tigrina


Correct Option: B
Explanation:
  • Chordata- The species having a spinal cord. 
  • Craniata- The species that have a cranium or skull.
  • Amphibia- The species which live on both land and water. 
  • Gnathostomata- Jawed vertebrates. 
  • Rana- genus 
  • tigrina- species 
Rana tigrina is the scientific name of the bullfrog found in India. We will start by seeing the common morphology(structure) of the frog. The frog has a spinal cord so it belongs to Phylum Chordata. The skeletal structure reveals the presence of a skull so Craniata. The frogs have also distinct jaws so they can be placed in the superclass Gnathostomata. Frogs live in both land and water-class Amphibia. and Rana is the genus.
So, the correct answer is 'Chordata, Craniata, Gnathostomata, Amphibia, Rana'.
