📖 1. Overview
Reaching 75 cm in length with legs outstretched and weighing up to 3.3 kg—about as much as a house cat—it is the world's largest living frog (anuran amphibian).
🌐 Wikipedia Summary ExtractThe goliath frog, otherwise known commonly as the giant slippery frog and the goliath bullfrog, is a species of frog in the family Conrauidae. The goliath frog is the largest living frog. Specimens can reach up to about 45 centimetres (18 in) in snout–vent length and 4.5 kilograms (9.9 lb) in weight. This species has a relatively small habitat range in Cameroon and Equatorial Guinea. Its numbers are dwindling due to habitat destruction, collection for food, and the pet trade.
🦴 2. Anatomy & Morphology
Lacking a vocal sac and unable to call, it instead pushes and moves heavy riverside rocks weighing more than half its own body weight to build stone-walled spawning pools for its tadpoles.
🔍 3. Ecology & Behavior
It can leap more than 3 m in a single bound and preys on bats, crabs, small snakes, and even turtles.
🇰🇷 4. Connection to Korea
It is a valuable species that demonstrates the physical size limits of amphibians and the evolution of parental care.
