Keelkonnad

Keelkonnad is a term that generally refers to the biological family Ranidae, commonly known as true frogs. These amphibians are found on every continent except Antarctica and are characterized by their smooth, moist skin, long hind legs adapted for jumping, and webbed feet. True frogs exhibit a wide range of sizes, from tiny species a few centimeters long to some of the largest frogs in the world, like the African bullfrog.

The diet of keelkonnad typically consists of insects, spiders, worms, and other small invertebrates. Some larger species may also prey on small vertebrates such as fish, other amphibians, and even small mammals. They are carnivorous and play a significant role in controlling insect populations. Reproduction in keelkonnad usually involves external fertilization, with females laying eggs in water, often in large masses or strings. The tadpoles that hatch are aquatic and undergo metamorphosis to develop into adult frogs.

Keelkonnad inhabit a variety of environments, including forests, grasslands, wetlands, and even deserts, provided there is access to water for breeding and moisture. Their skin is permeable and can absorb water, but it also makes them vulnerable to dehydration and pollution. Many species are sensitive to environmental changes, making them important bioindicators of ecosystem health. The conservation status of different keelkonnad species varies, with some facing threats from habitat loss, pollution, and disease.
