Answer 2

Explanation:

whale has 4- Chambered heart

The biggest heart in the world is inside the blue whale. It weighs more than seven tons. It's as big as a room. It is a room, with four chambers.

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

shark has 2 chambered heart

Sharks possess a single-circuit circulatory system centered around a two-chambered heart. Blood flows from the heart to the gills where it is oxygenated.
