They are green to brown in color with dark blotches on their dorsal side.
They are cousins of the aquatic frogs and live most of the time in the water.
First kept as a pet, then recently during the 1990s, it was deliberately introduced to a number of fresh water rock pools in Gozo, where in one it sustains a large population.
Though a prolific and invasive species, it is restricted to constant fresh water supply, so it cannot spread naturally on its own on arid Mediterranean islands.
This species is named for herpetologist Jacques von Bedriaga.
