| In order to study the benthic ecology of the “Messioua banc” (30 NM east off Zarzis, Southern Tunisia), a traditional Tunisian sponge fishing ground, four marine campaigns were conducted with the R/V “Hannibal” from October 2000 to August 2001. The objectives of three of these campaigns were field validation, focusing on the sampling of the Posidonia oceanica meadow and of the sponge population. However the goal of the fourth one, with the use of a multi-beam sonar SEABAT 9001 (Reson Co.), was the mapping of bottom of the surveyed area and the scanning of the Posidonia meadow and its sponge population. The field work allowed the study of sixteen stations covered by a dense meadow extending from 21 to 33 m depth, which present the highest density of... |

| Several marine campaigns aiming to collect marine demosponges for specific research projects on their taxonomy and biogeography and to study the phenology and distribution of Posidonia oceanica a long the Tunisian coasts were conducted these last 10 years. They allowed a scuba diving prospecting of the infra and circalittoral zones of 555 marine stations. This field work was an occasion to describe some bottom’s associations, to highlight the general state of the main communities, specially the Posidonia and the coralligenous formations, and to draw up a list of their mega benthic species. In general, both biota are well preserved along the Tunisian coasts. except for some black spots, mainly the one of the gulf of Gabes, where detailed analysis showed... |

| La revue des travaux réalisés jusqu’en 2003, relatifs à la systématique des spongiaires, à la bionomie benthique et aux inventaires de la biodiversité marine en Tunisie, ainsi que les nombreuses signalisations récentes, nous ont permis de dresser une liste de 143 espèces de démosponges en Tunisie. Elles se répartissent dans 65 genres, 37 familles et 13 ordres (dont 3 sous ordres), et sont représentées de façon non homogène dans les régions Nord, Sud et Est de la Tunisie. La région Sud est la plus riche aussi bien au niveau générique que spécifique. Ces espèces sont classées en trois groupes différents. Le premier groupe est composé de 33 espèces à large répartition géographique s’étalant du Nord au Sud de la Tunisie ; le second groupe est composé de 37... |
