Abstract
More than 2000 individuals belonging to four species of the genus Munida were collected during a survey of the benthic biology of the Porcupine Seabight. The bulk of the collection consists of M. sarsi, which occurs down to a depth of about 800 m in the Seabight. Data are provided on the relative abundance of this species at different depths, the relative growth of its chelae, chelar propodi and eyes, and its reproductive biology. More limited data are provided for M. tenuimana which overlaps with the lower part of the bathymetric range of M. sarsi and extends to about 1400 m in the Seabight. The new information on M. sarsi and M. tenuimana is compared with previous data on these species from other regions. The two remaining species, M. rugosa from the upper slope and continental shelf and M. microphthalma from mid-slope depths were obtained in insufficient numbers to provide significant biological information.
