The Goliath Frog, the largest living frog on earth, is facing extinction after a 50% decline in population in the last three generations.

The Goliath Frog reaches up to 13 inches long (32 cm) from snout to vent, and weighs up to 7.2 lb (3.25 kg). However, its tiny habitat range in Africa`s Cameroon and Equatorial Guinea makes it vulnerable to human-related habitat destruction.

At the peak hunting season between November and April, at least 20,000 Goliath frogs are hunted for they are considered a delicacy in south-western Cameroon, with one Goliath frog fetching up to $15, a pretty sum for the region.

Scientists estimate that Goliath frogs have been around for 250 million years, but we still know so little about them.

And if nothing is done to protect them, they could become extinct in just a few years.•
