Which of the following organisms live in both aquatic and terrestrial habitat during the course of its life?
Frog
Turtle
Frogs lay their eggs in water. The eggs hatch into tadpoles, which look very different from frogs. The tadpoles live exclusively in water and breathe through gills instead of lungs like an adult frog. The process of changing from a tadpole into an adult frog is called metamorphosis. The lungs grow and the frogs are able to breathe in the air too. During this time, the frogs live in the terrestrial habitat.
The major difference between tortoises and turtles is that tortoises dwell on land, while turtles live in the water some or nearly all of the time.
