Escape deficits induced by a biologically relevant stressor in the slug (Limax maximus).

For 7 consecutive days slugs (Limax maximus) were exposed to escapable, inescapable, or no light-heat stress in an escape task. On Days 8 and 9 they were tested in a different escape task. The slugs in the inescapable light-heat group had reliably longer escape latencies and more failures to escape than the slugs in the escapable light-heat group or the no light-heat control group.
