Question 34
Animals of colder regions and fishes of cold water have thicker layer of subcutaneous fat. Describe why?

Answer 1

Animals of colder regions and fishes of cold water have thicker layer of subcutaneous fat because fat acts as subcutaneous insulation of body for thermoregulation i.e, subcutaneous fat functions as insulating layer that prevents heat loss from the body in colder environment which helps them to survive in such adverse condition. Fat also functions as reserve food during periods of scarcity.
