Abstract: Populations of the limpet Acmaea scabra found high in the intertidal remain immotile and do not feed for long periods of time, while lower populations move and feed more frequently. Studies were carried out to determine whether any nutritional or metabolic adaptations enable these high populations to sustain themselves over these prolonged periods between feeding. Comparisons were made of glycogen content and respiratory rate between two populations; one at +2 feet in the intertidal, the other at +6 feet. It was demonstrated that the higher populations have greater glycogen stores and lower respiratory than the lower populations. The differences could represent an adaptation to survive for long periods between feeding.
