Frog Anatomy and Morphology Quiz

Frogs belong to the class ______ (phylum Chordata).

Adult frogs are ______ and do not have tails.

Frogs exhibit ______ during summer and hibernation during winter.

Frogs have highly ______ skin that absorbs water and helps in respiration.

Frog skin is glandular and secretes ______ and toxic substances for defense.

Frog

Carnivorous, tailless amphibians, widely distributed in India
Diverse frog species globally, including the Indian bullfrog (Hoplobatrachus tigrinus)
Vertebrates, classified under the class Amphibia (phylum Chordata)
Cold-blooded (poikilothermic), body temperature dependent on environment
Need to protect themselves from extreme heat and cold, through estivation and hibernation during summer and winter
Estivation is a summer dormancy period; hibernation is a winter one

Morphology

Larvae possess tails, adult frogs are tailless
Stout body, differentiated into head and trunk
External features include nostrils, protruding eyes, membranous tympanum (eardrum), slippery/warty moist skin, webbed limbs
Highly permeable skin, functions as respiratory organ, absorbing water and oxygen
Skin glandular, secreting mucus and toxins for predator defense
Skin color can range from brown/green to vibrant colors

Anatomy

Well-developed structures supporting the body plan
Structures play a role in crucial bodily functions
