There are over 5,000 species of frogs (and still counting). One of the groups include the poison dart frogs that are toxic and have interesting and vibrant color patterns on their bodies. There is another species called green tree frogs that are translucent green in color, and if you see their belly down on a piece of glass, you can watch the internal organs and the heart of the frog! The huge range of this species can be found all over the world, and hence, there are different habitats, but frogs are generally seen near semi-aquatic lands.
Frog Habitat
Most frogs start life in water and move onto land as adults. But not every species follows that pattern, some are adapted to live in trees, while others stay in the water their whole lives.
Frogs that live in deserts burrow into the ground and go into a dormant state called estivation during the dry season. When the rains return, they wake up. Frogs in colder regions hibernate in winter, burrowing into mud or under leaf litter. Some even freeze solid and thaw out alive in spring, which is a remarkable adaptation to cold climates.
Since the lifecycle of a frog is proportional to its habitat, let's consider it in detail.
Interrelation Between the Life Cycle and Habitat
- Frogs lay their eggs in water. Depending on the species, eggs vary in number, size, and shape.
- Within a few weeks, the eggs hatch into tadpoles (also called polliwogs). Tadpoles live underwater and often cling to pondweed.
- Tadpoles breathe through external gills. They feed on algae and plant matter in the pond.
- As the tadpole grows, its external gills disappear and are replaced by internal gills. Its tail gets longer.
- The tadpole then grows hind legs, and then front legs too. At this point it is still comfortable living in water.
- Metamorphosis begins: the tail shrinks and the tadpole becomes a froglet. It can now venture onto land.
- The tail disappears completely, and the froglet becomes a fully grown adult frog. It now hunts for food (insects, flies, and slugs) in the area around the pond.
Natural Habitat
- Frogs are seen almost everywhere; they exist in rainforests, forests, and caves; they can also be seen in deserts and on hilltops.
- The best places for frogs are places that are mucky and have a lot of bugs. An interesting fact about frogs is that they have an extensible tongue, which has a sticky surface, and they can flick it quickly to catch a bug.
- Frogs are mostly seen in swamps, marshes, ditches, streams and puddles, as these places have plenty of muck and insects.
Habitat Requirements
- The ideal conditions for their habitat should have the right temperature for the eggs to hatch.
- It should be devoid of fast-moving water, and lots of rocks and stems should be present where they can lay their eggs.
- Besides water, frogs require a habitat that provides them with food and shelter. The tadpoles need algae, weed, and small plants to eat, while big plants provide good shelter to hide. These amphibians spend a lot of time in the water; they hide from danger or predators inside the water.

5 quick questions about frog habitats, life cycles, and pond-keeping.
Creating a Habitat
If you want to keep frogs as pets, you can set up a habitat for them at home. You can buy a commercial frog aquarium or build one yourself, and in doing so, you will also be helping the environment!
Aquarium Habitat
Getting the right tank is important. There are several types of aquariums designed specifically for frogs, each suited to different species and their needs. Here is a quick overview so you can pick the right one.
Terrestrial tank: Terrestrial aquariums are apt for those that dwell in dry climates.
Aquatic tank: A standard water-filled tank for fully aquatic frog species. (Keep frogs and fish separate unless they are known to be compatible.)
Half-and-half tank: As the name goes, this has half water and half landmass setup, which will fit the bill for many species of frog.
Arboreal tank: These tanks are designed for tree frogs, which dwell on branches of trees.
Garden Habitat
You can also transform a section of your garden into a frog habitat. Along with the needs above, here are the steps to build and maintain a garden frog pond.
- Dig a pond and make sure the location is part-shaded and part-sunny, but not under a tree. The pond in the center should have 50 cm depth and the edges should be shallow and have a flat base.
- Cover the base with gravel, and place rocks, logs, and plants in and around the pond. Release some frogs in this pond.
With your own garden frog pond, you can watch the entire life cycle of frogs right at home.
