“Partula snails are incredibly valuable to the scientific community,” said Paul Pearce-Kelly, a senior ZSL curator. As a result, the authorities decided to get rid of these interlopers – by introducing a second snail, the rosy wolf snail (Euglandia rosea) to kill off the newly introduced pests. “Rosy wolf snails are incredible predators,” added Clarke. “There were around 120 different species of Partula snails in Polynesia,” Clarke added. At the same time, populations of the rosy wolf snail started to drop.
