Do furry animals lay eggs?
Their metabolic rates are lower than that of most other mammals. Adult monotremes don’t have teeth. Young platypuses do have tribosphenic molars, but they’re lost as adults. The adult male platypus is venomous.
Do marsupials have eggs?
They lay leathery eggs, similar to those of lizards, turtles, and crocodilians. Monotremes feed their young by “sweating” milk from patches on their bellies, as they lack the nipples present on other mammals. Most female marsupials have an abdominal pouch or skin fold where there are mammary glands.
Is a platypus the only mammal that lays eggs?

Are there any mammals that can lay eggs?
There are exceptions to every rule, some reptiles and fish bear live young, and some mammals lay eggs. Egg-laying mammals belong to a group called monotremes. Beside egg-laying, monotremes possess other traits that separate them from other mammals.
How does an animal hatch from an egg?
And many different types of animals have young that hatch from eggs. Even among egg-layers, there are some differences and varieties. Some animals mate before laying eggs, while in other species such as fish, males and females release gametes at the same time, and the eggs are fertilized in a medium such as water.
How many species of animals have pouches for their young?
However, these species of mammals with pouches for their young ones have been discovered to belong to the three hundred and thirty-five species (335 species) of the infra-class marsupial.
Why do animals have pouches on their bodies?
