This slug was seen in Budleigh Salterton and is actually a variation on the traditioal black variety. Very variable in colour, completely black specimens being commonest in the north, but also brick-red, orange and grey. The foot fringe is broad and often paler and redder than body. Tubercles large and elongate. When contracted and irritated, may rock from side to side for some time.
