Abstract

Larvae of vent shrimp from the Mid-Atlantic Ridge are known to disperse widely from the adult habitat. Experimental analysis of the temperature/pressure tolerance of the first zoeal stage of Mirocaris fortunata from the Lucky Strike vent field suggest that the upper limit of vertical distribution is determined by temperature. Conversely, the lower limit is controlled by the maximum pressure tolerance of the larvae.
