Because flamingos feed on food from salt water, they often drink seawater.
Their organisms have many mechanisms to help regulate osmosis—for example, salt glands on their beaks secreting brine, which is then removed through the nostrils.
Adult cassowaries have a black body with a blue head, a reddish cape, and two red wattles hanging down around the throat. The head is protected by a large casque made of bone tissue.
The neck color can vary in different individuals due to the habitat in which they live.
They are known for their distinctive way of swimming on their backs.
They raise their heads and front fins above the water level, which helps them with breathing, and their wide tails work like ballast to help them swim.
