Some snails prefer to escape from a direct attack. This changes the snail's center of gravity, enabling it to roll over and right itself. Jellison recorded three different measures of the snails following the introduction into their tank of sea star scent: the total distance the snail traveled, the shape of the path the snail followed (to measure whether the snail was in flight or just wandering looking for something to graze on), and the time the snail spent out of the water. Credit: Gabriel Ng . In some cases, snails are victims of predators introduced into their habitat, that is, animals that do not belong to their natural environment which can be very dangerous for them.
