Is a platypus a furry?
Platypuses have dense, thick fur that helps them stay warm underwater. Most of the fur is dark brown, except for a patch of lighter fur near each eye, and lighter-colored fur on the underside. The bill of a platypus, sometimes called a duck-billed platypus, has a smooth texture that feels like suede.
Can a platypus be blue?
Duck-billed, egg-laying platypuses just got a little weirder: It turns out their fur glows green and blue under ultraviolet (UV) light. But the trait is much rarer in mammals, and this is the first evidence of biofluorescence in egg-laying mammals, also known as monotremes, scientists reported in a new study.
Is kangaroo a monotreme?
Marsupials (e.g. kangaroo, opossum) and monotremes (e.g. platypus) differ from placental mammals in many characteristics, particularly reproduction. Marsupials have a few very large and very conserved chromosomes, while monotremes show a reptile-like size dichotomy and have a unique chain of ten sex chromosomes.
Why are monotremes only found in Australia?
Why are monotremes, mammals that lay eggs rather than give birth to live young, only found in the isolated region of Australia and New Guinea? Australia and New Guinea, however, broke away before more advanced mammals arrived, and thus monotremes remained. The only modern monotremes are the platypus and the echidna.

Can I buy a baby koala?
