platypus | Eggs, Habitat, Venom, & Facts

Natural history

Platypuses are generally solitary confinement, spending their lives either feeding along the bottoms of rivers, streams, and lakes or resting in burrows dug into the banks. They are highly energetic, feeding about endlessly while in the water, shoveling through streambed debris with their flat bills as they hunt for larval insects and fresh water crustaceans ( a favorite food ). The platypus uses its sophisticated electromechanical system to detect minute electrical signals given off by the muscles of its prey. After feeding, it retires to its burrow, the entrance of which is big enough to admit only the platypus and serves to squeeze overindulgence moisture from the fur.

Platypuses are not known to hibernate. however, they have an unusually low soundbox temperature for mammals ( about 32 °C [ 90 °F ] ). Studies have shown that they can maintain a ceaseless body temperature even after extended periods in water with temperatures vitamin a humble as 4 °C ( 39 °F ), a fact that puts to rest the belief that monotremes can not regulate their consistency temperature.

Form and function

Platypuses range in length from 38 to 60 centimeter ( 15 to 24 inches ) ; males are by and large larger than females. aquatic adaptations include the flat streamlined soundbox, dorsally placed eyes and nostrils, and dense waterproof fur that keeps the platypus well insulated. Long guard hair protect the indulgent undercoat, which remains dry even after hours in the water. The across-the-board webbing on the presence feet extends well past the hook and is essential in propelling the animal through the water. The paddlelike stern acts as a stabilizer during swim, while the back feet act as rudders and brakes.
