![]() ![]() Monotremes split off from the mammalian evolutionary lineage before the evolution of placentas, so they retain this distinctly reptilian method of reproduction. ![]() When the young (called puggles) finally hatch, they’re only the size of a jellybean. (The four species of hedgehog-like echidna are the only other monotremes alive today, and they too live in Australia as well as New Guinea.) Female platypuses typically lay between 1 and 3 marble-sized eggs, which they incubate for about two weeks in an underground burrow. Platypuses are monotremes, a type of mammal that lays eggs instead of giving birth to live young. One of the (arguably) weirdest elements of platypus biology is their reproduction. They’re One of Two Types of Mammals to Lay Eggs.Platypus GLP-1 is much longer lasting, and scientists think it could one day lead to new medications for diabetes. Humans produce GLP-1, too, and a modified version is already used in diabetes treatments. Called GLP-1 (glucagon-like peptide-1), the hormone promotes insulin release, which in turn lowers blood glucose levels. (One Vietnam War veteran described the pain as worse than being hit by shrapnel.) Victims also experience nausea, gastric pain, cold sweats, lymph node swelling, and muscle wasting in the envenomated area.Īnd yet platypus venom could one day help treat illnesses: Australian scientists recently discovered that platypus venom contains a hormone that could aid in diabetes treatment. While the venom isn’t fatal to humans, anyone unlucky enough to be jabbed can expect days of “ immediate, sustained, and devastating” pain that’s resistant to morphine and other painkillers. Scientists think that males use these spurs to compete with rivals during breeding season. Each spur is connected to a crural gland - or modified sweat gland- which creates a powerful venom. Male platypus have half-inch spurs on each of their hind legs. But did you know that their venom could also help treat diabetes? ![]() You might have heard that platypus are venomous.
