Goliath frog classification, habitat, ecology, conservation

Scientific name: Conran goliath


Kingdom: Animalia

Phylum: Chordata

Class: Amphibia

Order: Anura

Family: Conrauidae

Genus: Conraua

Species: goliath


Goliath frogs are known as the largest frogs in the world. They are 17 to 32 cm in length and about 600 to 3250 grams in weight. They have a high, broad body with a wedge-shaped head. Their back skin is dark brown and thick, and the inner skin of their abdomen is reddish-brown. The hind legs are short and strong, and both legs are very cobwebs. Their eyes are up to 2.5 cm in diameter.

The eggs of Goliath frogs and tadpoles are similar to all other frogs, even though their bulky size. A horizontal folding extends from the eye to the back of the eardrum. The toes are full and have large interdigital membranes up to the toes.

The second toe is the longest. The skin on the back and legs is grainy. The dorsal color is sienna green, while the belly part and the ventral part of the legs are yellow or orange. They have a high sensitivity but have no voice pockets and no wedding support. [1]Goliath frog – Wikipedia

Distribution and habitat

The Goliath frog is commonly found near and in sandy, low-lying streams flowing through the countries of Central Africa, Equatorial Guinea, and Cameroon. These rivers are generally oxygenated. Their real routes range from the last 200 km of the Sanaga Basin in Cameroon in the north to the last 50 km of the Benito River Basin in Equatorial Guinea in the south.

The stream paths where these frogs live are frequently found in densely populated, moist, and extremely hot areas. Although they usually live in rivers during the day, they often roam the world at night. [2]ADW: Conraua goliath: INFORMATION (animaldiversity.org)

Behavior and ecology


As in most amphibians, water is vital for their reproduction. The golden frog does not have a vocal cord, it does not create the cry of cohesion, a pattern common in frogs and toads. Hundreds of eggs hatch in a few thousand eggs, each about 3.5 mm in length and often close to aquatic plants.

All semicircular and found in or near the river There are three main types of nests:

  • Initially, it removes part of the river pond.
  • In the second part, an existing swimming pool is added, separating it from the river.
  • Finally, the diggings a pond about 1 m wide and 10 cm deep, sometimes moving large stones intimate the building.

This explains the size of the giant frog, as large frogs can be very good at moving heavy objects to build their nests. The elders were also shown guarding their nests at the time of night. While it has not been deep-rooted, there are signs that the nest was built by a male, while the female guarded the nest with eggs. The development of the larvae takes among 85 and 90 days.

Adults eat crustaceans, insects, fish, and other amphibians, but at times they also eat birds, small animals, and even bats.


Goliath frogs have no vocal cords and are often considered bad. As they shout, the big frogs keep their mouths open and hiss.


Dark green frogs cover them well with moist stones covered with moss where adult frogs are found. Goliath frogs have only been known to catch humans, although some predators may do so.

Conservation status

The IUCN estimates that gold frogs are on the verge of extinction due to a 50% debility in population over the last three generations. Major dangers to these species include food, habitat demolition due to human settlements, drowning, commercial logging and exports for agriculture and wildlife reserves, the sale of pets, and competing for frog species.

The habitats of other large frogs, including Monte Alen National Park in Equatorial Guinea, have been described as protected areas. All 3 wildlife sanctuaries in Litoral province have been permitted as secure areas in Cameroon.

The Government of Equatorial Guinea has set a perimeter of 3 hundred per year for frogs that can be shipped. Thus, conservation efforts within the community and slavery programs must also be taken into account to maintain the size of the population.

Other important facts

  • Goliath frogs can catch and eat bats (found after examining the contents of the closed Goliath frog).
  • The main culprits are giant lizards such as Goliath frogs, snakes, crocodiles, and Nile monitors.
  • The breeding season for Goliath lasts from July to August.
  • People make semicircular basins on riverbanks using stones and gravel. They are worried about starting to rule and finding opportunities for unity.
