Octopus

Octopuses have three hearts, unlike most animals. This unique circulatory system helps them survive underwater.

Function of Two Hearts

hearts pump blood to the gills for oxygen exchange. This allows efficient respiration in water.

Function of the Third Heart

The third heart circulates blood to the body. It ensures oxygen reaches all organs.

Blue Blood

Their blood contains copper-based hemocyanin, making it blue. This helps in oxygen transport in cold environments.

Heart Behaviour While Swimming

The main heart stops beating when they swim. This reduces energy consumption during movement.

Oxygen Regulation

Their multiple hearts help in oxygen regulation. This is crucial for deep-sea survival.
