Question

Rana tigrina is the zoological name of
A. Frog
B. Garden Lizard
C. Tiger
D. Krait

Answer 1

Hint:- Scientific or zoological naming of species by binomial nomenclature is a formal and universally standardized method for recognizing and classifying organisms. This type of nomenclature consists of two terms where in the first term is the genus of the organism and the second part is the precise species under the genus that it belongs to.

Complete Answer:-
The standardized binomial nomenclature helps identify an organism with ease because there can be only one scientific name by which the animal can be referred to, as against the numerous local names it may possess that results in confusion. For animals, these names are assigned by the ICZN (International Commission on Zoological Nomenclature).

Given that the first part of the name that is capitalized refers to the genus of the organism, this portion helps narrow down closely associated species. For example, lions (Panthera leo), tigers (Panthera tigris) and jaguars (Panthera onca) are species that are clubbed under the common genus Panthera.

Rana tigrina refers specifically to the Indian bullfrog or Asian Bullfrog due to their population distribution in areas such as Bangladesh, India, Myanmar, Nepal, etc. These groups of amphibians prefer to stay near freshwater sources and avoid coastal areas.

Thus, the zoological names of the given options are as follows:
A. Frog - Rana tigrina
B. Garden Lizard - Calotes versicolor
C. Tiger - Panthera tigris
D. Krait - Bungarus caeruleus

Therefore, the correct answer is option A - Frog.

Note:- - Rana tigrina is now known as Hoplobatrachus tigerinus.
- It is important to not get misled by the terms “tigrina” or “tigerinus” which is like “tigris” of “Panthera tigris”. That is why it is pivotal to primarily recognize the organism’s genus by the first term and then narrow down the species by second term.
