The Complete Guide to Animals That Lay Eggs: Types, Care and More

Many animals reproduce by laying eggs rather than giving birth to live young. This method of reproduction is called oviparity. Here are some examples of animals that lay eggs:

1. Birds

Birds are perhaps the most well-known group of animals that lay eggs. They lay hard-shelled eggs that are usually incubated in a nest by the parents until they hatch. Bird eggs come in various sizes, shapes, and colors, depending on the species.

2. Reptiles

Reptiles, such as turtles, snakes, lizards, and crocodiles, lay eggs. Reptile eggs have leathery or calcified shells and are deposited in suitable nesting sites. The eggs are then left unattended, and the young hatch after a specific incubation period.

3. Amphibians

Most amphibians, including frogs, toads, and salamanders, lay eggs. Amphibian eggs are typically laid in water or moist environments. They have a jelly-like coating that helps protect the developing embryos. After hatching, amphibian larvae undergo metamorphosis to become adult individuals.

4. Fish

Many species of fish lay eggs as part of their reproductive process. Fish eggs are usually fertilized externally, with the female releasing the eggs and the male fertilizing them with sperm. The eggs may be deposited in nests or scattered in the water, depending on the species.

5. Invertebrates

Various invertebrates lay eggs as part of their reproductive strategy. Examples include insects (such as butterflies, beetles, and bees), spiders, scorpions, crustaceans (such as lobsters and crabs), mollusks (such as snails and clams), and many others. Invertebrate eggs come in different sizes, shapes, and forms, depending on the specific species.


Animals that lay eggs encompass a wide range of species, from birds and reptiles to amphibians, fish, and various invertebrates. This reproductive strategy allows for the survival and propagation of diverse organisms across different habitats and environments. The eggs provide protection and nourishment for the developing embryos until they are ready to hatch and embark on their independent lives.
