Question

Branch of zoology connected with the study of amphibians and reptiles is
A. Ichthyology
B. Ornithology
C. Malacology
D. Herpetology

Answer 1

Hint: Zoology is the branch of biology that deals with the study of animals. Kingdom Animalia consists of several classes of animals. Amphibia and Reptilia are examples of these classes.

Complete answer: Amphibians are a group of animals that can live both in water and land. Larvae of these animals are aquatic. Meanwhile, reptilians are crawling and creeping creatures that are adapted for terrestrial life. Amphibians comprise a group of animals that include Salamander, Ichthyophis, Newt, trilotriton, etc. Keep in mind that frogs and toads are amphibians that are common in our surroundings. Reptilians have their body covered with dry and hard scales or scutes. They are cold-blooded animals and lack external ears. Testudo(tortoise), Chameleon(tree lizard), snakes, etc are examples of reptilians. Reptilians are characterised by internal fertilisation and direct development. The branch of zoology that deals with the study of fishes is known as Ichthyology.
i. Ornithology is the branch of zoology that deals with the study of birds. Birds belong to the class Avia. The presence of feathers for flight is the characteristic feature of this class of animals.
ii. Malacology is the branch of zoology that deals with the study of molluscs. Molluscs are the bilaterally symmetrical organisms. Their body is covered by a calcareous shell that protects these animals from predators.
iii. The branch of zoology that deals with the study of amphibians and reptiles is called herpetology.
Hence, the correct answer is option D.

Note: Amphibians are reptiles and are closely related organisms. Both are cold-blooded organisms and are poikilothermic in nature. The body of an amphibian is moist and soft in nature while reptiles have a body covered with scales.
