Which animals are found both in water and on land ?

  • A.Pisces
  • B.Reptilia
  • C.Amphibians
  • D.Cyclostomata

Answer: C

The animals found both in water and on land are amphibians.

The word means 'double life'. Frogs, toads and salamanders typically lay eggs in water, and their larvae (tadpoles) live in water and breathe with gills. The adults develop lungs and can live on land, though they breathe partly through moist skin and return to water to breed.

Pisces (fishes) and Cyclostomata (lampreys and hagfishes) are aquatic throughout life. Reptilia are mainly land animals with dry scaly skin, and even turtles and crocodiles do not have the amphibians' two-stage life.
