Nicole Boury-Esnault
Nicole Boury-Esnault is a retired French researcher of sponges, formerly at Centre d'Océanologie de Marseille, Aix-Marseille University. Research In 1995, Nicole Boury-Esnault and Jean Vacelet discovered a species of carnivorous sponges of the genus '' Asbestopluma'', during an exploration of a shallow cave in the Mediterranean. Caves can recapitulate the environment of the deep sea-bed due to the darkness and lack of nutrient, permitting the study of deep-sea-like regions in shallow areas of water. Carnivorous sponges, lacking the normal filter feeding apparatus, had been previously discovered during deep-sea trawls and presumed to be damaged since they did not have a known feeding mechanism. The discovery of members of the family in shallow water meant that they could be experimentally tested, which is when Boury-Esnault and Vacelet observed feeding on small crustaceans. Later they also reported on a member of the genus which used both carnivory and methanotrophy to survive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Vacelet
Jean Vacelet is a French marine biologist who specialises in the underwater fauna of the Mediterranean. After earning his licence at the Faculté des Sciences de Marseille and learning to dive in 1954, he specialised in the study of sponges at the Marine station of Endoume, and there he has stayed faithful to both sponges and place for more than half a century. His research has included all aspects of sponges: taxonomy, habitat, biology, anatomy, their bacterial associations, and their place in the evolution of multi-celled animals. He has studied them not only in the Mediterranean but in the Indian Ocean and the Pacific. Exploration of underwater grottoes, together with Jacques Laborel and Jo Hamelin, revealed the existence of sponges dating from very ancient geological periods and the unexpected existence of carnivorous sponges, and surprisingly, the grottoes in some ways mimicked life at much greater depths. He earned one doctorate in 1958 and his doctorat ès-sciences, unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Sea Sponges
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, h ...
