Animals That Lay Eggs

key notes :

Oviparous Animals:

• Animals that lay eggs are called oviparous animals.
• These animals reproduce by laying eggs from which their young hatch.

Types of Oviparous Animals:

• Birds: All birds lay eggs, usually in nests, and incubate them until they hatch (e.g., hens, eagles, penguins).

• Reptiles: Many reptiles lay eggs, often in sandy or warm places (e.g., snakes, turtles, crocodiles).

• Amphibians: Amphibians like frogs and toads lay eggs in water.

• Fish: Most fish lay eggs in water. Their eggs are often released in large numbers.

• Insects: Many insects lay eggs, such as butterflies, ants, and mosquitoes.

Egg Protection:

• Some animals, like birds, build nests to protect their eggs.
• Others, like turtles, bury their eggs in the sand.
• Insects often lay eggs in specific locations to provide food for the larvae when they hatch.

Hatching:

• Eggs contain all the necessary nutrients for the embryo to develop.
• Once the development is complete, the young animals hatch out of the eggs.

Advantages of Laying Eggs:

• Laying eggs allows animals to produce many offspring at once.
• It allows animals to leave their young in a safe place while they continue other activities.

Examples of Egg-Laying Animals:

• Birds: Parrots, chickens, ducks.

• Reptiles: Lizards, geckos, alligators.

• Amphibians: Frogs, newts, salamanders.

• Fish: Salmon, clownfish, goldfish.

• Insects: Bees, grasshoppers, beetles.
