There is only one species of platypuses. It is not "poisonous", but adult males have venomous spurs on their ankles. Apart from several species of shrews and the Cuban solenodon, platypuses are the only venomous mammals.Female platypuses do not have venom, but they are born with spurs. These spurs fall off by the time the young female is about a year old.
No. The female platypus is not dangerous in any way. The male platypus has a venomous spur, but young females lose their spur by the time they are twelve months old, and it is never venomous.
Yes. Their ability to dig long burrows give them some protection.
A few mammals possess venom. Shrews have a toxic saliva. Some monkeys secrete a poison from their "armpit" and lick it to give them a venomous bite. The male Platypus has spurs on theirs back legs that can inflict a painful, venomous sting.
Adult male platypuses have venomous spurs on their ankles. Through this spur, they can deliver a poison strong enough to kill a small dog, and to cause almost paralysing agony to an adult human. Platypus venom contains a protein which lowers blood pressure, inducing shock.
Platypuses do not have any "poisonous" parts, but adult males have venomous spurs on their ankles. These spurs are attached to a venom gland in either thigh of the platypus.
Platypuses are not poisonous at all, as "poisonous" indicates that something is dangerous if you ingest (eat or drink) it.Adult male platypuses have venomous spurs on their ankles. There is nothing either venomous or poisonous about their bill. The bill is not called a beak.
Adult male platypuses have venomous (not poisonous) spurs on their ankles, and it is not the hollow spur itself that is venomous. The spur is attached to a venom gland in the platypus's thigh. It is not known why platypus spurs are venomous, but it is believed to be a defensive mechanism to deter predators. There has been limited research done on platypuses, so it is unknown whether the spur is used in territorial disputes between the males of the species, as only the males have spurs. Through these spurs, they can deliver a venom strong enough to kill a small dog, and to cause almost paralysing agony to an adult human. Platypus venom contains a protein which lowers blood pressure, also inducing shock.
platypus Technical point #1: Since only the male platypus has the venomous spurs, and only the female platypus lays eggs, there would actually not be any venomous egg-laying mammals. Technical point #2: There are no egg-laying marsupials. The platypus belongs to the monotremes.
Since only males have the venomous spurs - and production of the venom increases during breeding season - it is possible that the venom is not for protection but is just t used to win a mate n competition with other males. It does have an incidental utility for defense however since anything or anyone injected with the venom will certainly not want to tangle with a platypus and those spurs again.
Definitely the giant anteater would be much more dangerous. A platypus would only pose a danger if it is improperly handled. However, an angry or threatened giant anteater is capable of disemboweling a human with one swipe of its front claws.
There are two misconceptions in this question. First, there are no egg-laying marsupials. All marsupials give live birth. Second, there are numerous venomous mammals. Many species of shrew, as well as the Cuban Solenodon, are venomous mammals. The only egg-laying mammal that is venomous is the platypus, which ejects venom through a hollow spur on each ankle. Only maturemales have spurs and can eject venom. The platypus is a monotreme, not a marsupial. Monotremes are egg-laying mammals.
