The goliath frog is a resident of the African continent: it lives in Equatorial Guinea and Cameroon. It is the largest frog in the world.
Many frogs do not disdain dirty water, because they are often found in swamps, but goliath frogs can only live in crystal clear water with a high oxygen content.Goliath Frog (Conraua goliath).
The appearance of giant frogs
The length of only one body of a goliath frog, excluding large long paws, is about 32 centimeters, and body weight can reach 3.25 kilograms.
In appearance, these giants as a whole resemble ordinary frogs. Sexual dimorphism in goliath frogs is expressed in body length: females are larger than males. The skin color is greenish-brown, and the inside of the legs and belly is whitish or yellowish. The back is covered with wrinkled skin.
Goliath Frog Lifestyle
Since goliath frogs cannot tolerate dirty water, they live in tropical fast rivers and waterfalls. In addition, they are demanding on water temperature. In the rivers and streams where these huge frogs live, the water never drops below 22 degrees. In addition, goliaths need high humidity, so they do not come across in highly lit places.This species of frogs lives in oxygen-enriched water.
Adults are very shy and cautious. It is difficult to catch such a frog, since goliaths have excellent eyesight, they notice movement over a distance of more than 40 meters. Most of the time they prefer to hide in the rocks near the waterfalls. If there is any danger, the goliath frog instantly jumps into the foamy water, hiding from the enemy. In the water, it can be about 15 minutes, hiding among the stones at the bottom.
When the danger is over, the frog slowly pops up, showing the tip of the muzzle above the water, and then bulging eyes, and only then the rest of the body rises. Further, the frog slowly floats to the shore, making short tremors. She jumps, climbing on the rapids and ledges of stones. In this case, the frog always chooses a position so that it is convenient to make a jump if necessary, if there is a danger.
Giant Frog Diet
Goliath frogs feed on various insects, larvae, crustaceans, spiders, worms, and other animals. Often, smaller frogs become their victims. Goliath grabs the victim, making a sharp head movement or jump. Like their brethren, goliaths grab the victim with their jaws and tongue, then press down and swallow it whole.In addition, goliath frogs are caught from nature and transported abroad.
Breeding Goliath Frogs
The breeding season of these frogs falls on the dry season. The female lays in about 5 days about 10 thousand fairly large eggs, whose diameter is 5 millimeters. From the egg to the formation of an adult, 70 days pass. At birth, the length of the tadpoles is only 8 millimeters, and in 45 days their size already increases to 48 millimeters, then the tail falls off the tadpole and it becomes a frog.
Goliath Frog Population
Today, goliath frogs within the range are considered an endangered species. From the 80s to the 2000s, the number of these huge frogs decreased by almost 2 times. The main threat to the population is the capture of these frogs by the local population, in order to eat their meat.The giantess-goliath is the largest of modern frogs.
These giants have long been an object of persecution for people: lovers of exoticism, gourmets and numerous collectors prey on them. Being a big frog is quite difficult, the weight and growth of goliaths have become a significant problem for them, because they are slow and slow. Having made just a few jumps, the frog gets tired, so it is easy to catch. These huge frogs have long been the subject of attention of zoos and private collectors. A huge number of individuals were caught from nature and taken to the United States, where jumping competitions were held between goliaths.
And of course, the destruction of their habitual habitat, with the aim of farming and deforestation of the rainforests, causes enormous damage to the population. The habitat of goliath frogs is annually reduced by several thousand hectares due to the destruction of trees. About half of the natural habitats of goliaths are in serious danger. In addition, environmental pollution is a negative factor: poachers pollute water with chemicals for fishing.
For goliaths who can live and lay their eggs only in clear water, this is an environmental disaster.These frogs are considered pure animals, their meat tastes sweet, in addition, it is considered useful for pregnant women.
Goliath frogs are abundantly supplied to local food markets and restaurants. Restaurants pay a pretty good price for a large individual.
It is worth noting that attempts to breed goliath frogs in artificial conditions end
failures, which is why these defenseless giants need to be handled by people.
The WWF is trying to preserve the habitats of goliath frogs, which are simply melting before our eyes. Recently 3 reserves have been created, and it is also planned to establish control over the basins of several rivers. If these measures are implemented, this will save the unique huge frogs and change the situation of the population in the direction of increase.
