Question

How many mammals can lay eggs?

Answer 1

There are only three known species of mammal that can lay eggs: the monotremes. These are the platypus and two species of echidna. All three species lay eggs and have a combination of features from both reptiles and mammals.

Answer 2

There are only a few mammals that can lay eggs or scientifically known as monotremes. These include platypuses and echidnas, which are both found in Australia and New Guinea. Monotremes are unique in the way that they lay eggs instead of giving birth to live young like other mammals. They also have a mix of reptilian and mammalian characteristics such as laying eggs, having a bill-like structure for feeding, and having mammary glands to nurse their young.

Answer 3

Among mammals the only group that lay eggs is the monotremes. Monotremes are a small and unique group of egg- laying mammals that includes the platypus and echidnas.

Answer 4

Among mammals, the ability to lay eggs is limited to a unique group called monotremes. Monotremes are a primitive group of mammals that includes the platypus and echidnas (also known as spiny anteaters). These fascinating creatures are the only living mammals that lay eggs instead of giving birth to live young. There are only five extant species of monotremes: Platypus (Ornithorhynchus anatinus): Found in Australia, the platypus lays small, leathery eggs and incubates them in a burrow. After hatching, the young are nourished with milk produced by specialized mammary glands. Short-beaked echidna (Tachyglossus aculeatus): Found in Australia and New Guinea, the short-beaked echidna also lays eggs. The female deposits a single leathery egg into a pouch-like structure called a "pouch" located on her abdomen. The egg hatches after about 10 days, and the young echidna continues to develop in the pouch. Western long-beaked echidna (Zaglossus spp.): Found in New Guinea, the western long-beaked echidnas are a group of three species that lay eggs and have similar reproductive processes to the short-beaked echidna. These five species represent the only known mammals that retain the ancestral trait of egg-laying. All other mammalian species give birth to live young through various reproductive methods such as placental birth or marsupial pouches.

Answer 5

There are only five known species of mammals that lay eggs, and they are all monotremes. These include the platypus and four species of echidnas ( also known as spiny anteaters).

Answer 6

There are just five surviving types of vertebrates that lay eggs, and they are known as monotremes. These egg-laying vertebrates include: 1. Platypus (Ornithorhynchus anatinus) 2. Short-bent echidna (Tachyglossus aculeatus) 3. Western long-bent echidna (Zaglossus spp.) - three species 4. Sir David's for some time hooked echidna (Zaglossus attenboroughi) - an as of late found species. These monotremes are novel among well evolved creatures for their regenerative strategy, as they lay eggs as opposed to bringing forth live youthful. They are tracked down in Australia and New Guinea.
