The platypus and the echidna both belong to the group of animals known as monotremes. The platypus and two species of echidna are the only creatures in this classification, which is characterised by the feature of being egg-laying mammals, yet they are not birds or reptiles. This means that both creatures hatch their young from eggs (which, incidentally, the echidna incubates in a pouch, but the platypus does not), yet the mother of each species feeds her babies with milk from milk glands - not from teats like placental mammals and marsupials do.
One of the characteristics of a platypus is that it has an unusual duck-like bill, and as such, does not have teeth - an unusual characteristic for a mammal. Instead it uses grinding plates to crush its food. The echidna, also known as the spiny ant-eater, also does not have teeth. Instead it has a long, sticky tongue which it uses to catch and eat termites and ants.
Echidna and platypus young stay in a burrow after they are hatched. However, the echidna develops a rudimentary pouch during breeding season, into which it lays and incubates its young. The platypus does not have a pouch.
Both creatures have sharp claws for burrowing. The echidna can quickly burrow into the ground to escape predators, while the platypus uses its claws to dig out a burrow in the riverbank.
Surprisingly, both the platypus and echidna like the water. Not so surprisingly for the platypus, as it must hunt in the water for its food. Regarding the echidna - though its body shape would seem to be awkward for swimming, the echidna actually enjoys water when it can find it, and it is believed the echidna regulates its temperature through swimming.
In broad classification terms these two animals are considered to be cousins, but their genetic and physical characteristics differ significantly more than the genetic and physical characteristics of human cousins.

There is no such thing as a "Eucalyptus platypus".
Ornithorhynchus anatinusThe original name was Platypus anatinus, from Greek and Latin words meaning "flat-footed, duck-like". After realising that the name "platypus" had already be given to a group of beetles, the scientist involved assigned the platypus the scientific name of Ornithorhynchus anatinus, the first word of which means "bird-like snout".
They give birth to live babies, but the platypus lays eggs.

The two definitive characteristics that make the platypus a mammal are: 1. It nurtures its young on mothers' milk. 2. It has fur. No other group of animals both these characteristics.
Male platypuses can produce venom.
No. The platypus has always been a platypus. It is not derived from the beaver, otter, duck or any other animal. There is no actual evidence of evolution in the platypus's line. Fossils of possible platypus ancestors indicate that, if it did indeed have other ancestors, they shared the same characteristics the modern platypus has today.

The platypus is not endangered. The Australian Government lists the platypus as "common but vulnerable". The International Union for Conservation of Nature lists the platypus as "least concern". Platypuses are now strictly protected by law
