Heart. Oxygen is pumped around its enormous body by an equally massive, four-chambered heart. Weighing some 900kg – and the size of a Mini car – the blue whale’s heart beats once every 10 seconds, pumping 220 litres of blood through its body, and beats so loudly it can be heard from 3km away through sonar equipment.

Do whales have skeletal muscles?
Cetaceans exhibit a wide range of body masses and sizes1,2, though the gross distribution of skeletal muscle, particularly the epaxial and hypaxial components, appears to be similar in all species, providing a somewhat alike tail-stroke power for swimming.
How many teeth has whale?

How are whales different from other marine mammals?
Whales, porpoises, and dolphins are marine mammals, and like all mammals, they require oxygen to survive. Unlike other sea creatures such as fish which use gills to extract oxygen from the water, whales must come to the surface to breathe as they possess lungs and a blowhole rather than gills.
