وہ کونسا جانور ہے جس کی جلد کے نیچے چربی کی موٹی تہہ ہوتی ہے جو انہیں سمندر کے سرد درجہ حرارت سے بچاتی ہے؟
Explanation
  • Blue Whales have a thick layer of fat, known as blubber, under their skin that helps to keep them warm in cold water.
  • This layer of fat can be up to 30 cm (12 in) thick and makes up about 50% of their body weight.
