Resumo: | The present work is an ecological study about Peracarid Crustaceans living on rocky bottom in infra and circalittoral zone.  A sampling method for hard bottom is presented in the first part.  A biocenotic study permits, in a second part, to describe the distribution of the populations. Affinity index values, computed by Bravais-Pearson correlation coefficient, show three faunal associations assigned to the upper-infralittoral, deep-infralittoral and circalittoral zone. The relations between species and environment are studied by mathematical approach.  A multiple linear regression analysis shows the influence of light penetration and turbidity factors. A factor analysis gives two principal components, interpreted as biotic environment and density of organic particles into water.  This work establishes the fundamental influence of biotic factors (trophisme and biotic environment) on the species distribution. [NOT CONTROLLED OCR]
