Tailed-slugs
Family Aglajidae
updated
May 2020
Where
seen? These slugs are sometimes seen on some of our shores. They appear to be highly seasonal. Many kinds we see only once and never again.
Features: Long, cylindrical body with a pair
of 'wings' (called parapodia) which fold over the centre of the body
as well as a pair of 'tails, one longer than the other. They have
tiny shells which are internal.
What do they eat? Some tailed slugs are carnivores and eat their prey whole, crushing
them with hard calcareous plates in the gizzard. Their prey include
other slugs, flatworms, acoel flatworms and polychaete worms.
Some have well developed structures to track down their prey by following
the prey's mucous trail. Others are herbivores. |
