Frogs, like toads, are insect-eating animals.
Frogs have teeth only on the upper jaw, and toads do not have them at all, so there is nothing to bite off pieces of food. Due to these features, the food of frogs and toads is swallowed entirely.
They catch their food with their original tongue – long, strong, and bifurcated at the end. It is immediately thrown out of the mouth in the direction of the victim, and then, because it is sticky, it comes back with stuck prey. Another curious fact is that food enters the esophagus through the eyes. When blinking, the eyes sink deep, pushing food into the esophagus.
What do frogs eat in nature?
Toads have a great appetite. The main food for them are invertebrates: worms, insects, bedbugs, spiders, caterpillars, clams, etc. More than half (60%) of all insects eaten by toads are pests of agricultural land. These animals also eat slugs. Many gardeners see on the strawberry berries unpleasant slugs, which are usually hidden in the daytime in the wet ground, and in the evening go out to eat the soft juicy fruit of sweet ripe strawberries. It is very difficult to fight with them. This is exactly where toads are great helpers.
An adult frog is a carnivorous animal. The frog eats mosquitoes and other insects. For the lake toad, the prey is a fish fry. In connection with this, fish farms are caused considerable damage. Hiding in shallow water, the frog waits for a flock of fry, and after waiting for them, it sharply opens its mouth, where the flow of water involves a pile of fishes. With the fry in his mouth may be tadpoles.
In the stomachs of frogs are often present and plant remains, because to their tongue adheres part of the leaves and flowers on which the prey sat. All this is quickly swallowed by the frog, and then it goes again to get new food.
What do frog tadpoles eat?
The larval stage in different types of frogs is very similar. Hatched from the eggs tadpoles have no hole in the mouth. The germinal stock of nutrients ends in about seven days when it reaches a length of 1.5 cm. During this period, there is a rupture of the mouth and begins independent feeding.
The main food tadpoles are unicellular algae. Random impurities that are assimilated by the frog’s body together with the main food are mold fungi, protozoa flagellates, and other microorganisms.
The mouth of the tadpole is well adapted to scrape off algae plaque and is like a “beak” surrounded by fringe lips. The lower one has rough outgrowths and is larger than the upper one. Feed tadpoles during the day, being in warm water on the shoals and near the coast, forming mass clusters (up to 10 000 pieces). Not all of them survive because the frog larvae serve as food to birds, fish, and many other inhabitants of the reservoir.
Tadpoles turn into little frogs. They are quite voracious. In the filled state, their stomach volume exceeds 1/5 of the total mass.
Another curious detail – if there is not enough animal food in the pond tadpole and winters in the larva stage, until spring, postponing its transformation into a predator.
What do frogs eat at home?
Xenopus is especially popular with aquarists, whose skin excretions have the effect of natural antiseptic, well-disinfecting water. Such a frog is usually planted in an aquarium with fish that have contracted some kind of infection. However, there must be a mesh septum between them, as the frog can eat its “patients”.
Usually, amphibians living in an aquarium eat live food: earthworm, daphnia, moths, etc. The frogs can eat their “patients”. Because frogs do not move much in captivity, they tend to be obese. Feed them no more than twice a week. They may also eat thinly sliced nonfat meat or fish.
And what do frog tadpoles eat at home? In the very first days, they are suitable for powdered milk (good and baby formula). In the second week, you can introduce a mixture of insects and herbs after a good steaming in the oven or in the sun to avoid various rotten processes.
Beef liver and small moth are introduced in the last days of metamorphosis to strengthen the body of small frogs, but all this should be crushed to the smallest size.
