UNTERWASSER-BEOBACHTUNG VON CRUSTACEA DECAPODA REPTANTIA UND STOMATOPODA MIT HILFE EINES FOTOSCHLITTENS

Abstract

1. The pictures taken by the photosled in 13 lowerings in the upwelling area off NW-Africa and off Morocco show 13 species of Decapoda Reptantia and Stomatopoda. Only specimens which could be identified to generic level at least are dealt with and all others that can only be ranged in higher taxa (above generic level) are ecluded from consideration. 2. The perceptibility-limit of specimens is about 2-3cm carapace breadth. 3. Most of the photographed species could also be obtained by trawls. 4. The photosled is shortly described with special regard to improvements. It is a useful tool for biological mapping of the sea floor.
