Very little is known about whether the platypus has a good sense of smell or not.
However, when hunting for food underwater, the platypus closes its nostrils, along with its eyes and ears, so it probably does not have a particularly acute sense of smell. it does not require scent to hunt for its prey, as its bill is equipped with sensitive electroreceptors that detect the tiny electrical impulses made by aquatic insects, larvae, worms and crustaceans.
Platypuses breed with other platypuses.
Platypuses do not "threaten" other species. Platypuses feed on a variety of small invertebrates, but they do not threaten these species, as the creatures are plentiful.
Platypuses are shy creatures which do not readily interact with other animals.
No. Platypuses do not eat mangroves or any other plant matter.
No. Platypuses are not found in China or any other region of Asia. Platypuses are endemic to eastern Australia, which means they are not found in any other country or continent at all.
No
Compared to other animals, our sense of smell is poor. A lot of animals can smell things from miles away! :)
Platypuses are one of the 2 mammals that lay eggs. The other is the echidna.
No. Platypuses are endemic to Australia alone, meaning that they are not found in any other country.
other platypuses and other aquatic mammals
Platypuses are monotremes. In other words, they are mammals that have a sense of electroreception. But no, platypuses are not exactly electric: they do not produce electricity, and there is only 1 species of platypus. There are no other species. So, there is no such thing as electric platypuses.
Platypuses do not eat earthworms or other terrestrial worms. They eat aquatic annelid worms.
