Platypus a presentation by christina romanenko


The platypus range is in Eastern Australia


The species was once found in the Adelaide Hills and Mount Lofty Ranges of South Australia. Nowadays it is extinct from that state, except for the introduced population on the western end of Kangaroo Island.


Platypuses occur in freshwater systems from tropical rain forest lowlands and plateaus of far northern Queensland to cold, high altitudes of Tasmania and the Australian Alps.


Diet of the Platypus consists mainly of the benthic invertebrates, particularly the insect larvae. The species also feeds on free-swimming organisms: shrimps, swimming beetles, water bugs and tadpoles, and at times worms, freshwater pea mussels and snails. Occasionally the animals catch cicadas and moths from the water surface. In captivity, the Platypuses are often fed freshwater crayfish (Yabbies).

physical characteristics

social behavior

Platypus’ are solitary animals, but do tend to share small bodies of water. Males and females are differentiated by the males having a sharp hollow spur on their hind legs which join to a gland in the groin which produces a venom capable of causing great pain and incapacity in humans and can be lethal to small mammals.The platypus is a solitary animal which does not live in social groups.

life cycle


Platypus reproduction is nearly unique. It is one of only two mammals (the echidna is the other) that lay eggs.



Domain: Eukaryota-The Platypus has Eukaryota cells with membrane bound organelles.

Kingdom: Animalia

The Platypus responds to stimuli and are multicellular organisms.

Phylum: Chordata

The Platypus has a ventral nerve cord, pharyngeal slits and a tail. There are also three subphyla of Chordata, the Platypus belongs in the Vertebrata.

Class: Mammalia

The Platypus produces milk for the young through mammary glands like all mammals. It also is warm blooded and has three specialized bones in the ear for hearing, also it has no visible ears.

Order: Monotremata-A monotreme is simply a mammal that produces young by eggs instead of having live-birth.

Family: Ornithorhynchidae-The Platypus is the sole survivor of the whole family of the Ornithorhynchidae. They are characterized by having the duck-bill, a flat tail for swimming and have hard plates in the mouth, instead of teeth.

Genus: Ornithorhynchus-Any Ornithorhynchus is a member of the family, Ornithorhynchidae, in which case, it must be a Platypus!

Species: Ornithorhynchus anatinus
