No. Platypuses do not use electricity: they use electroreception.
The bill of a platypus has sensitive electroreceptors which pick up tiny nerve and electrical impulses generated by crustaceans and other animals that inhabit the bottom of the creek or river.
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 have teeth, but hard bony plates which they use to grind the food.
It is illegal to kill platypuses. One of the biggest threats to platypuses used to be the use of fishing nets in freshwater rivers and creeks, as the platypuses would become entangled in the nets and drown. Using such fishing nets has been outlawed.
Yes, platypuses do have eyes, and they use them whenever they are on land. Platypuses close their eyes when they dive and hunt underwater for food. They do not need to see underwater, as they use the electroreceptors in their bills to detect living organisms underwater.
No. Platypuses do not have teeth. They have grinding plates in their bill, which they use to crush their prey before swallowing it.
No. Platypuses do not use mimicry of any description.
No. Platypuses are wild animals; they do not have to have any commercial use. In the Kate 1800s and early 1900s, platypuses were hunted for their fur, as they have beautiful velvety pelts. However, this practice was banned when platypus numbers dropped to critical levels, and platypuses, like all native Australian mammals, are now protected by law.
Platypuses are mammals, so they use the same type of respiratory system as other mammals - mouth, nose and lungs. They do not breathe underwater.
No. America does not have platypuses. Platypuses are endemic to eastern Australia.
Platypuses is the correct spelling.
The only mammal that can sting is the Platypus. Male platypuses have spurs on their back ankles with from which they can inject poisonous DLPs (defensin-like proteins). Female platypuses and echidnas also have these back ankle spurs, but only male platypuses can use them.
Platypuses were not invented. They were discovered by someone.
