| The heteropods are transparent planktonic animals, whose systematic position has undergone considerable reappraisal since the last century. It was Lamarck who, in 1812, created the order Heteropoda, which he placed between the Cephalopoda and the fishes, and brought together the genera Carinaria, Firola and Phyllirhoë. Later, Cuvier (1829) added to these the genus Atlanta. [NOT CONTROLLED OCR] |

| Cytogenetic abnormalities arising both in mitosis and meiosis are known to be common in bivalves. Here we review result obtained from the observations of somatic aneuploidy in different populations of the commercially important Pacific oyster, Crassostrea gigas. The oysters studied were either (1) produced in IFREMER hatcheries between 1986 and 1999, (some of these were part of the EU funded programme GENEPHYS); or (2) collected from wild populations along the French Atlantic coast. Chromosome numbers were scored from 30 mitotic metaphases in gill tissue per individual studied. Aneuploid cells (2n - X) were observed in all the 13 populations studied. A highly significant negative correlation was observed between the level of aneuploidy and growth, i.e.... |

| Mangrove oysters include various species that are also present on different coasts. In the southern part of the Atlantic Ocean, Crassostrea rhizophorae has been observed along the southern coast of America and Crassostrea gasar along the western coast of Africa. Fifteen populations of these oysters were sampled from these two geographic areas. Their polymorphism was studied on the 16S mitochondrial fragment both by par sequencing and RFLP analysis. Some samples' caryotype were also analysed. Two haplotypes were identified: C. gasar was found in Africa, but also for the first time in South America, whereas C. rhizophorae was only found on the coasts of South America. |

| Chromosomes of six cupped oyster species were studied using karyometric analysis alter conventional Giemsa staining, and silver staining, Karyotypes of Crassotrea angulata (nine metacentric and one submetacentric chromosome pairs), C. sikamea (nine metacentric and one submetacentric chromosome pairs), C. virginica (eight metacentric and two submetacentric chromosome pairs), C, ariakensis (eight metacentric and two submetacentric chromosome pairs), C, gasar (six metacentric and four submetacentric chromosome pairs), and Saccostrea commercialis (eight metacentric and two submetacentric chromosome pairs) are distinguishable by the number and position of the submetacentric chromosome pair and by the location of nucleolus organizer regions, Comparative... |

| The histological structure o f the digestive system and its histophysiological changes during digestion are described in the adults of 6 species of Atlantidae. The results are interpreted functionally and discussed from the point of view of systematics. The digestive tract of the Atlantidae comprises an oesophagus functioning as a crop, a small stomach and a short intestine. A pair of tubular salivary glands and a digestive gland (hepatopancreas) are associated, but oesophageal and rectal glands are lacking. The radular apparatus has the usual prosobranch characters. The digestive tract is totally devoid of mucous cells. Several unicellular glands are in the buccal wall and the anterior part of the oesophagus. There is an apocrine secretion in the crop.... |

| With the histological techniques used to study Heteropod 13, 14 larvae, the histological structures of planktonic larvae are described at a stage close to metamorphosis; species are chosen among families of Mesogastropods (Lamellariidae, Eratoidae, Cypraeidae, Naticidae) whose phylogeny is close to the Atlantacea superfamily (= Heteropoda) according to the Taylor and Sohl15 classification. The mantle, mantle cavity, foot and digestive tract are described in depth. |

| Some scanning electron microscopy observations have been conducted on different species of Prosobranches from the Roscoff area: Trochidae, Calliostoma zizyphinum, Gibbula magus, Gibbula cineraria, Gibbula tumida, Cantharidus clelandi, Cantharidus exasperatus, Cantharidus montagui, Cantharidus striatus; Skeneidae, Skenea serpuloides, Skenea cutleriana, Skenea nitens; Skeneopsidae, Skeneopsis planorbis. Observed with closer attention are the protoconch and the first juvenile spiralial whorls.
