Is A Duck Billed Platypus A Mammal Or A Marsupial?

A marsupial IS a mammal. A mammal is an animal that produces milk (mammary glands) for its offspring. A marsupial is an animal that carries its young in a pouch where the mammary glands are located. The platypus is related to the Echidna which is the only other mammal known to lay eggs and not give live birth.

The Echidna however is a marsupial and can incubate its eggs in its pouch where the offspring get their milk when hatched. A Platypus DOES NOT HAVE A POUCH. A platypus lays eggs in a burrow, and curls around them to keep them warm until they hatch. The mother then feeds the young from its mammary glands.
So a Platypus is a mammal, but is not a marsupial.

The duck billed platypus is a strange creature, for it is a mammal but lays eggs.

It is one of Australia's most bizarre looking animals and difficult to classify for a number of reasons:
* is it a mammal because it produces milk
* is it a reptile because it lays eggs
* or is it an amphibian?

Platypuses are amazing creatures that have thick set bodies covered in brown fur, short feet and a large duck-like bill which detects electrical impulses in the water and helps the platypus to find its prey.

Adults are about 50 centimetres long and weigh in at around two to five kilos. The males have spurs on their hind legs which inject venom that can be fatal to some animals and agonisingly painful for larger ones.

The platypus is an air breather, but it's natural environment is the water. It is an excellent swimmer and moves with difficulty over land. The name platypus comes from Greek and means 'flat feet'.

The Duckbill Platypus is a mammal that lays eggs.

Key Features:
:has the beak of a duck and the body of a mammal-it even lays eggs
:Hunts with it's eyes and ears closed, using it's highly sensitive bill to detect the minute electrical feilds given out by it's prey
:Male produces enough venom to kill a dog

A mammal

Yes, it is a mammal because it hey are warm-blooded, unlike reptiles, and they have fur, unlike reptiles which have scaly skin. They are also monotremes, meaning they are egg-laying mammals.

They are mammals, and they also lay eggs ,weird.

it is a mammal because it nurses its young (mammary glands=milk)

The Platypus (Ornithorhynchus anatinus) is a semi-aquatic mammal endemic to eastern Australia, including Tasmania. Together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth to live young. It is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), though a number of related species have been found in the fossil record.
The bizarre appearance of this egg-laying, venomous, duck-billed, beaver-tailed, otter-footed mammal baffled European naturalists when they first encountered it, with some considering it an elaborate fraud. It is one of the few venomous mammals; the male Platypus has a spur on the hind foot that delivers a venom capable of causing severe pain to humans. The unique features of the Platypus make it an important subject in the study of evolutionary biology and a recognizable and iconic symbol of Australia; it has appeared as a mascot at national events and is featured on the reverse of the Australian 20 cent coin. The platypus is the animal emblem of the state of New South Wales.^[4]

I'm sure its a mammal

A duck billed platypus is both a mammal and a marsupial. A mammal is a creature which gives milk to its young. A marsupial is a creature which carries its young in a pouch.
Duck billed platypuses both give milk to their young and carry them in pouches, therefore they are both mammals and marsupials.They are very strange creatures.
