First record of the fountain bladder snail Physa fontinalis (Linnaeus, 1758) (Gastropoda: Hygrophila) in Morocco

Alien and invasive species pose a significant threat to global biodiversity, causing costly economic and environmental damage. Recent field surveys in northern Morocco have led to the discovery of the fountain bladder snail Physa fontinalis (Linnaeus, 1758), providing the first evidence of its occurrence in North Africa. The exotic species is currently only known from one locality in Morocco, future surveys may reveal its presence elsewhere. It is essential to monitor its spread within invaded areas and conduct studies to improve our understanding of its biology, ecology, and potential impact on native communities in North African freshwaters.
