The African Clawed Frog has conquered science labs AND the swamp. Now it's arming up with arc-trajectory grenades to blast bouncing bugs back to the bug world. Parabolic precision. Zero regret. Maximum carnage.
The African clawed frog (Xenopus laevis) was the world's first pregnancy test! In the 1940s, injecting pregnant women's urine into female Xenopus frogs caused them to lay eggs within 12 hours. This 'Hogben test' was used in hospitals worldwide.
African clawed frogs have been transported worldwide for laboratory use and have escaped into the wild, where they've become invasive species. They may have spread the deadly chytrid fungus that has devastated amphibian populations globally.
Their name comes from three sharp black claws on their hind feet, used to tear apart food. Unlike most frogs, they're entirely aquatic — they never come on land and drown if kept out of water.
African clawed frogs have no tongue and no vocal sac. They can make clicking sounds by snapping the small cartilages in their larynx, but communicate primarily underwater through vibrations detected by their lateral line system.
