A red crayfish spotted in Berlin's Tiergarten park in August. Originally from North America, red swamp crayfish that grow up to 15 centimetres long have been creating quite a fuss amongst passersby in the capital. "As the water rises, they leave the sinking ship.”The red swamp crayfish is on the European Commission’s list of invasive alien species. They argue the crayfish are to be kept as far as possible from Europe because they displace native crayfish populations. According to NABU, the crustaceans could be dangerous for native crayfish species because they can carry and spread fungal diseases.
