Question

Limbs are webbed for swimming in:
A. Tortoise
B. Turtle
C. Terrapin
D. All of the above

Answer 1

Hint: Reptiles have been found to thrive on land and in water and based on their habitats their limbs are modified for particular purposes like swimming in water or walking on the land. Limbs are meant for locomotion and in many cases to hold firmly to a surface. Some reptiles have limbs modified in a way that can be used as attacking organs like the presence of claws when in danger.

Complete answer:
Option A: Tortoise spend their life exclusively living on land and a webbed limb would not be beneficial for them to thrive on the terra. On the other hand, they have got limbs modified for walking on land.
Thus, Option A is incorrect.
Option B: Turtles mostly live-in aquatic habitats. However, they have flippers for swimming instead of webbed feet.
Thus, Option B is incorrect.
Option C: Terrapin live an amphibious life on land and water and have webbed feet for paddling in water to enable swimming.
Thus, Option C is correct.
Option D: All of the above is not correct since turtles and tortoises do not have webbed feet.
Thus, Option D is incorrect.

Hence, Option C. Terrapin is the correct answer.

Note:
The limbs of reptiles are jointed and usually have five toes. Five is the original number of toes on the limbs of vertebrates. Most reptiles have this number, even though crocodiles have only four digits on their hind legs. They are almost always armed with claws. Snakes are however apodus lacks limbs as they have crawling locomotion through their bellies.
