4. Aug: A left-handed hermit crab...
A left-handed hermit crab living in small snail houses along sandy beaches is wanted! The south-claw hermit invades the Waddensea in warmer years coming from south-western regions. In 2008 it first appeared in Northern Frisia, in 2018 it was first reported from Denmark. The crabs freeze to death in cold winters and vanish from German Bight. The South-claw hermit differs from the common hermit crab in having a very large left claw, dark spots on its legs and a very pugnacious character. It inhabits small snail houses in the surf zone of beaches and can bury itself quickly with its housing. As the actual distribution of the species under warming conditions of the Northsea is unclear we kindly ask to report sightings especially from the northern Waddensea.
