Question

Enlist osmoregulatory adaptations is terrestrial animals?

Answer 1

Answer:

(i) For water conservation the body is covered by means of a water proof covering which prevents the evaporation of water from the body.

The water proof body covering may be of horny scales (as in certain reptiles), feathers (as in birds) and hair or fur (as in ma­mmals).

(ii) The loss of water through urine and faeces is checked by various mechanisms. In reptiles and birds the water from the faeces is absorbed by rectum and cloaca.

Further, in birds and mammal the water from the urine is absorbed by Henle’s loop in the uriniferous tubules of the kidneys.
