To determine which physiological properties contribute to temperature adaptation in the squid giant axon, action potentials were recorded from four species of squid whose habitats span a temperature range of 20 degrees C. The environments of these species can be ranked from coldest to warmest as follows: Loligo opalescens>Loligo pealei>Loligo plei>Sepioteuthis sepioidea. Action potential conduction velocities and rise times, recorded at many temperatures, were equivalent for all Loligo species… CONTINUE READING
