Species of gastropod
Allognathus hispanicus (now known as Allognathus balearicus) is a species of land snail in the family Helicidae, the true snails. This species is endemic to Mallorca, one of Spain's Balearic Islands.[1] The common name is "caragol de Serp" (snake snail), due to the pattern of its shell.
The snail lives in cracks in rocks and walls, and is only active when it rains.[1]
