The Platypus responds to stimuli and are multicelluar organisms. One strong clue that platypuses may be bird-mammal hybrids is the fact that in research appearing in the journal Nature Grützner et al. The platypus, like Superman, is none of the above. Echidnas, or spiny anteaters, are the only other mammals that lay eggs.When the female platypus is ready to have her young, she will burrow down inside the ground on the riverbank and seal herself into one of her tunnel rooms.

When an animal feeds their young ones with milk from their mammary glands, they are automatically classified as a mammal. After around ten days the eggs are hatched. They make up an evolutionary branch separate from the marsupials (e.g., kangaroos, koalas, and wombats) and placental mammals (the most common type of mammal, which includes everything from squirrels to whales to humans).

The platypus lives in and near lakes, rivers, and streams in eastern Australia. An Aboriginal dreamtime story about the platypus (one indigenous name for the animal is Dharragarra) explains its origin as the product of a courtship … In fact, it should be noted that platypuses are not the only existing egg-laying mammals. They are a species of primitive mammals called monotremes. Like the Human Genome Project, this undertaking sought to map the entire platypus genome to understand how an animal with such a hodgepodge of traits could have evolved. The milk is usually extracted from the pores of their skin, and then later collected on the grooves of their stomachs. It's classified as a semi-aquatic mammal because it spends a good amount of time on land as well as in the water. Is it a plane?

Despite its closer relationship to reptilian ancestors, many of the most fascinating features of the platypus evolved independently.
