Make up your mind for all these interesting facts about frogs for kids. Frogs are the amphibians that belong to the Anura order. One of the oldest frog fossils is believed to have been evolved some 265 million years ago and was named as ‘proto-frog’. These amphibians inhabit extensively across the subarctic and tropic regions, with the largest population exists in the tropical rainforests. Of all the vertebrate groups, frogs are the most varied vertebrate with 4,800 species around the world. The adult frog exhibits cleft tongue, folded limbs, and fat body. These species have no tail. Frogs are mostly found in freshwater and on dry lands and are believed to be perfectly adaptable for dwelling underground or in trees. Frogs have glandular type of skin which, in some species, is embedded with toxic secretions thus making them uneatable. Frogs are the close relatives of toads. The skin color of frogs varies from grey, brown to the green with some species reflect a glowing pattern of yellow.
These types of animals are known to lay eggs in water. The hatching takes place in larvae known as tadpoles that contains tails and gills. The frogs diet is classified into three classes; herbivores, omnivores, and planktivorous. There are a few numbers of frogs that lay eggs on land. The adult frogs are exclusively carnivorous and they primarily rely on small invertebrates. However, the omnivorous species feed on fruits. When the breeding season begins, frogs tend to produce several kinds of vocalizations that display numerous complicated behaviors such as to draw female’s attention for mating, to get rid of predators, or to usually survive. More than one-third of frogs are believed to be threatened globally as the population decline is getting worse.
- Frogs have neither tail nor claws. They have meshed toes, large eyes, shiny skin, extended ankle bones, and elongated rear legs. Frogs have short vertebral column.
- The frog’s skin allows the oxygen to pass easily which is why they can be found even in places with no or less oxygen since they can respire through their skins.
- One of the foremost causes of decline in population is due to the fact that frog’s skin is too much vulnerable to the surrounding environment. It should keep its skin soggy all the time as there are poisonous substances in the air that can pass into the bloodstream and thus causing death.
- The length of the frogs range from 10 mm (0.39 inch) to 300 mm (12 inches); the smaller species such as Brachycephalus didactylus can be easily found in Cuba and Brazil.
- They have three eyelid membranes and have no connective tissue.
- Unlike toads, frogs do have teeth but the lower jaw does not have teeth and frogs mostly swallow its prey as a whole. With the help of its claws, frogs grasp its prey strongly so as to swallow it completely.
- Depending entirely on species, frog’s legs and feet are varied. The tree-dwelling species have distinctive feet in comparison to the ground-dwelling species or those living in burrows and holes.
- These animals should move rapidly in order to catch its prey and at the same time to get away from the natural predators.
- How webbed the frog’s feet is, depends on the amount of time those species spend in water as compared to land.
- The frog’s skin is capable to absorb water and thus helps in maintaining the body temperature.
- Frogs are the cold-blooded animals and for the same reason they need to assume appropriate patterns to adjust their temperature. The skin color is employed for thermo-regulation. This color becomes darker as the temperature falls down.
- The frogs that tend to protect themselves through camouflaging are mostly nocturnal and they are known to hide during the daytime. There are few species that are adept to alter their skin color in order to get away from predators.
- The frog’s skin allows the carbon dioxide and oxygen together with water to enter into the bloodstream. The skin contains quite a large numbers of blood vessels that enables oxygen to permeate. When on land, frogs employ lungs to breathe.
- The frog’s teeth are primarily used for holding the prey or food for swallowing. However, these teeth are not used for eating or chewing its prey, they are too weak to do this.
- One of the strange frog facts is that their eyes aid in swallowing down the prey.
