| Abstract |
When discovered in 1985, Rimicaris exoculata and Chorocaris chacei (Williams & Rona, 1986) were assumed by most to be blind. Downwelling light at intensities useful for vision does not reach depths greater than 800-1300 m (rev. in Lakin et al., 1997), while the shrimp are found at depths of arrow right 700-3900 m. Nonetheless, R. exoculata possesses a dorsal organ with cellular, biochemical, and physiological characteristics of a retina that appears to be adapted to transduce the dim light emitted by the hydrothermal vents around which they feed (rev. in O'Neill et al., 1995).We have also examined the morphology of the eyes of R. aurantiaca (Martin et al., 1997; Nuckley et al., 1996), C. chacei (Lakin et al., 1997), C. fortunata (Kuenzler et al., 1997), and A. markensis (Wharton et al., 1997). Neurochemical analyses of the brain of R. exoculata are underway (Curra et al., 1996). Electrophysiological recordings of concentration-dependent sulphide sensitivity from the antennal nerves of Rimicaris (Renninger et al., 1995) have provided insight into the mechanisms whereby vent shrimp might locate active hydrothermal systems. |
