There is just one species of platypus, and that is ornithorhynchus anatinus.
Platypuses are solitary animals and generally live alone.
Platypuses reproduce just once a year.
Platypuses are not cannibalistic. They do not eat their own kind.
It is not known how many platypuses are killed each year, but it is not as many as there used to be. Platypuses are no longer hunted for their pelts, and fewer of them are drowned in fishing nets as laws have come into effect to help protect them more. Floodwaters kill platypuses - they are mammals, and must breathe air, and young or weak platypuses can quickly drown in fast-moving floodwaters.
Platypuses live in burrows that they dig on the banks of freshwater creeks, rivers, lakes and dams. They line the end of the burrow with leaves and other dry vegetation.
No. America does not have platypuses. Platypuses are endemic to eastern Australia.
Platypuses do not have pregnancy. Although they are mammals, they are monotremes, which is the small group of mammals which lay eggs. Platypuses lay between one and three eggs at a time, once a year.
No. Platypuses have no interest at all in peanut butter (or peanut paste as it is still known in many parts of Australia).
It is usual for platypuses to make hundreds of dives every day in order to find sufficient food.
Platypuses breed just once a year. Each breeding season they lay between one and three eggs.
Platypuses is the correct spelling.
Platypus research has always been difficult as platypuses are shy and elusive creatures. Even today, it is not known how many platypuses there are. However, what is known is that there were far fewer in 1950, due to platypuses being hunted for their pelts, and accidental drownings in fishing nets. They are now protected, and it is believed that platypus numbers are back to similar levels that they were prior to European settlement.
