Are amphibians oviparous or viviparous

Answer 1

An echidna is an egg-laying mammal, meaning it is oviparous. The echidna and the platypus are the only mammals that are oviparous. They belong to the unique group of mammals known as monotremes. Although egg-laying, both of these mammals nurture their young on mothers' milk.

Answer 2

The platypus is oviparous. It is monotreme, which is an egg-laying mammal. The only oviparous mammals are the monotremes, and they include the platypus, the short-beaked echidna and the long-beaked echidna.

Answer 3

Oviparous because the young hatch after the egg is laid.

Answer 4

Echidnas are hatched from eggs. They are monotremes, or egg-laying mammals.

Answer 5

All amphibians are oviparous. That means that they lay eggs. To increase the odds that some offspring will survive, frogs usually lay many, many eggs.
