3 mammals that lay eggs
The class of mammals is divided into three subclasses. The egg-laying primitive mammals, the marsupial mammals and the subclass that also includes humans, the higher mammals. There are only a few species that belong to the subclass of prehistoric mammals. Only these lay eggs and are mainly found in Australia or New Guinea.
1. Mammals that lay eggs - the platypus
The scientific name of the egg-laying mammal native to Australia is Ornithorhynchus anatinus. After the systematic classification, the mammal is classified into the subclass of prehistoric mammals and then further into the order of monotremes. Even though the platypus can lay eggs, there are many exceptions to being classified as a mammal. The typical body temperature of the platypus is lower than that of actual mammals. The aquatic and mostly nocturnal platypus lives exclusively in southern to southeastern Australian freshwater areas.
2. The long-beaked echidna - a mammal that lays eggs
The long-beaked echidna is one of the mammals that lay eggs. This extraordinary genus probably includes 3 species. The long-beaked echidnas also belong to the subclass of prehistoric mammals and, like the platypuses, are classified in the order of monotremes. The endangered animals live primarily in the forest areas of New Guinea. Due to persistent deforestation and specially trained sniffer dogs, the egg-laying mammals in New Guinea are increasingly threatened.
3. The Australian short-beaked echidna also lays eggs
In contrast to the long-beaked echidna, there is also the type of short-beaked echidna. In contrast to the terrestrial echidnas, the short-beaked echidnas live exclusively on the Australian continent. The smaller species can also be distinguished by the fact that it weighs less, a small one Body size and yellowish to yellow-black spines, similar to those native to Europe Hedgehog, owns. But the short-beaked echidnas are also classified as a subclass of prehistoric mammals and in the order of monotremes. This means that the short-billed platypuses are one of the few exceptions to the mammals that lay eggs.
