An egg-laying animal is called oviparous. Many animals lay eggs. Many reptiles, birds, fish and almost all amphibians lay eggs, as well as many arthropods. If the question… means which mammals which lay eggs, the answer is monotremes. The only known monotremes are the platypus, the short-beaked echidna and the long-beaked echidna.
how meny animals lay eggs
It is generally accepted that the two vertebrate groups that lay their eggs in water are Fish and Amphibians. However, this is not strictly true, as not all amphibia…ns lay their eggs in water. Many species of frogs lay their eggs in water, but not all do, e.g. the Corroboree frog. Also, frogs of the genus Pristimantis lay their eggs on land, where they do not undergo a tadpole stage, hatching as fully metamorphosed baby frogs. Some amphibians do not even lay eggs. Some species of frogs even give birth to live young, such as members of the African genus Nectophrynoides and other species found in the Andes and Central America. There are also some salamanders which give birth to young which are either larvae, or already metamorphosed. Caecilians are a type of amphibian, rather like a worm, which give birth to fully metamorphosed young.
All mammals (excluding the platypus and echidna), very few reptiles (such as the boa constrictor and rough snouted gecko), and certain species of fish and other marine animals… (though very few) give life birth rather than laying eggs.

ive have seen eggs like that befor look up what animals lay SMALL green eggs for an better answer
reptiles lay leathery hard eggs and have scales some live on land Correction: Reptiles do not have scales, but scaly skin. There is a difference. Also, not all reptiles liv…e on land, and not all reptiles lay eggs. Some species give birth to live young.
Laying eggs in groups makes them easier to keep warm and safe and increases chance of the hatchlings' survival. Birds keep eggs in nests, where it is necessary to lay eggs in …groups to facilitate feeding and care-taking. Fish lay eggs in groups so that predators cannot eat all of the eggs because there are so many in one place at one time.
In Animal Life
The sub-group of mammals which lay eggs are called monotremes. This group includes the platypus and the two species of echidna.
All groups of animals lay eggs. The one most commonly defined as non-egg-laying is the group known as mammals. Almost all mammals give birth to live young. The exception to …this are the three species of monotremes , or egg-laying mammals, and they include the platypus and the two species of echidnas. Within the other vertebrate groups, only the "Birds" are all egg-layers. There are some species of fish, reptile and amphibians which do not lay eggs.

I'm not exactly sure, but I do know that a dinosaur called the Pterosaurs laid soft eggs.
