The platypus is the most unusual animal on the planet, for many reasons. The
platypus is an oddity and one of very few mammals to lay eggs.
Strangely, such peculiarities as its rubbery duck bill and webbed feet help to
arouse interest and indeed, even fascination.
Two hundred years ago, academics at the British
Museum were deeply suspicious of the latest specimen to arrive from the Antipodes.
... Those colonial pranksters were obviously trying to pull
off a hoax, perhaps even scientific fraud.
Scientists at first believed the specimen was the handiwork
of a clever taxidermist, constructed using the body parts of different

bearing the scars of attempts to prove it false.
Australia had produced some unique flora and fauna, this creature was just too weird. If it were true, it was a
zoological freak, a paradox - an egg laying mammal, without nipples, that breathes air but spends most of its
waking hours under water, eyes tightly closed and using it's duck-like bill to "sense"
the creature was difficult. The British scientist Dr George Shaw, in 1799, christened it Platypus anatinus
(flat-footed, duck-like animal). In 1800, a German biologist named Blumenbach named it Ornithorhynchus paradoxus
(bird's beak animal, a paradox).
scientific convention would have Shaw's name stand, it was discovered that the name platypus had earlier been given
to a genus of wood-boring beetles, so the strange little beast became Ornithorhynchus anatinus (bird-like

they are very expensive to keep in a laboratory.

There is nothing negative about this animal.
Cockatoos and emus can be difficult for farmers but platypus are not a problem, they regulate their own
population," she says. "People really react positively to them.
Platypuses are important in their own right;
they are beautiful and unique creatures and a symbol of Australia.
Not only are
they cute and furry, platypus also serve as indicators of the state of the rivers and streams. As a higher-order
carnivore, their existence in a particular area relies on the waterway being healthy enough to support the

400 grams of invertebrates each night, or they starve, and they feed continuously for about 12 hours. It is common
for them to move five to six kilometers each night.

platypus teeth have been found in sediment associated with dinosaurs, which means they have been around for between
