Answer: Goliath frog
Answer: Their snout
The goliath frog (Conraua goliath), otherwise known commonly as the giant slippery frog and the goliath bullfrog. The goliath frog is the largest living frog. Specimens can grow up to 13 in in length, and weigh up to 7.2 lb.
They have a relatively small habitat range in Cameroon and Equatorial Guinea. Its numbers are dwindling due to habitat destruction and its collection for food and the pet trade.
Goliath frog eggs and tadpoles are about the same size as other frogs despite their very large adult form.
Dorsal coloration is green sienna, while the abdomen and ventral part of the limbs are yellow/orange. They have acute hearing, but no vocal sac, and also lack nuptial pads.
The goliath frog is normally found in and near fast-flowing rivers with sandy bottoms. Although generally staying in the rivers during the day, they often emerge on land during the night.
The egg masses consist of several hundred to a few thousand eggs, and often attached to aquatic vegetation.
There are three main nest types, all semi-circular in shape and located in or near a river: In the first they clear a section in a river pool. In the second they expand an already existing pool, damming it off from the river. In the final they dig a pool, roughly 3 ft wide and 4 in deep, sometimes moving quite large stones in the process.
Adults have also been shown to guard the nests at night. Although not confirmed, there are indications that the nest is constructed by the male, while the female guards the nest with the eggs. Larval development takes between 85 and 95 days.
Goliath tadpoles are herbivorous and feed on a single aquatic plant, Dicraeia warmingii (Podostemaceae), found only near waterfalls and rapids, which may help explain their restricted range.
Adult goliath frogs feed on insects, fish, crustaceans, small reptiles, and small mammals.
It is preyed upon by snakes, Nile crocodiles, Nile monitors, and humans, among others.
The goliath frog can live up to 15 years in the wild. In captivity, they can live up to 21 years.
The primary threat to the goliath frog is hunting, as it is considered a food source in its native range. To a lesser extent they are also threatened by habitat loss and degradation. Due to their classification as an endangered species, the Equatorial Guinean government has declared that no more than 300 goliaths may be exported per year for the pet trade, but few now seem to be exported from this country.
