The life cycle of a frog consists of three stages: egg, larva, and adult. As the frog grows, it moves through these stages in a process known as metamorphosis. Frogs are not the only animals to undergo metamorphosis; most other amphibians also undergo remarkable changes throughout their life cycles, as do many species of invertebrates. During ...
That's because some sources will include only the stages of frog eggs, tadpoles, and adult frogs while others will include tadpoles with front legs, tadpoles with hind legs, and froglets in their description of the life cycle of a frog. The four main stages of a frog's life are generally held to be eggs, tadpole, froglet, and adulthood.
The developmental stages of most frogs are the egg stage, various tadpole stages, the froglet stage and the adult frog stage. The complete growth cycle of the frog generally takes between 12 and 16 weeks. The life cycle of a frog begins when the male frog mates with the female and fertilizes her eggs.
Many frogs undergo a stage of life between egg and adult known as the tadpole stage -- it's their larval stage. During this stage, frogs change both physically and behaviorally. According to Animal Planet, the metamorphosis from egg to adult can take 10 days to two years to complete, depending on the species of frog.
The Life Cycle of a Frog. Frogs are amphibians, which means that they can live in water or on land. They go through several stages of life before they become adult frogs and during those stages, they live only in water. Stage 1: Egg. A frog begins life as a fertilized egg. A female frog lays a lot of eggs at one time in a pond.
Life Cycle of a Frog Life Cycle of a Frog. 1 - Egg . The first stage is the egg stage. Eggs are usually laid in or near water. A frog can lay thousands of eggs at once. The eggs are laid in large groups. There are covered in jelly which makes them slippery. The jelly protects them from other animals eating the eggs.
Frogs lay many eggs in a mass or spawn, which serves to protect most of the eggs from predators. The male frog fertilizes the eggs as the female lays them in water. That is, the eggs are fertilized outside the female’s body. Each frog egg is a single cell but is an unusually large one that is visible to the human eye.
Spawn (egg-mass) While in the amplexus position, the male frog fertilizes the eggs as they get are laid. Frogs tend to lay eggs single eggs in masses, whereas toads usually lay eggs in long chains. Some frogs leave after this point, but others stick around to watch over the little ones. Some have very unusual ways of caring for their young.
