Oysters whose bodies are more swelled and fat with a whitish-yellow colour are females. Immediately after spawning the larvae are whitish-yellow(the mother oyster is said to contain "milt"). … The spawned eggs and the developing larvae lie protected in the mantle cavity … until the larvae are a few days old.  1, fiche 1, Anglais, - mother%20oyster

(...) the process of "torsion" involves a rotation of the mantle [of a young prosobranch gastropod], and [the] juvenile shell, with its enclosed viscera, through an angle of 180 degrees in relation to the velum(from which the head later develops) and the foot. As a result the mantle cavity comes to occupy an anterodorsal position, while the coiling of the shell assumes the endogastric direction typical of the adult gastropod. Effects of this torsion on the cells from which various organs of the adult animal later arise are far-reaching. Thus, when they develop, the nerve cords connecting the cerebral and pleural to the visceral ganglia are found to be crossed(...) rather like a figure 8, instead of being parallel. The gut has been twisted into a loop. It is, moreover obvious that the positions of the left and right ctenidia, osphradia, hypobranchial glands, heart auricles, and kidneys of the ancestral untorqued form become transposed as the result of torsion, so that when, as in most prosobranchs, only one of each of these organs remains, this, although now on the 6ft-hand side, represents the original right-hand organ.  1, fiche 2, Anglais, - torsion

[...] à la suite de [la] flexure [anopédieuse] amenant le sac viscéral vers l'avant, et avec lui le manteau qui l'enveloppe ainsi que la cavité palléale qui les sépare et contient les branchies, les Gastéropodes subissent une "torsion" de 180 degrés amenant le complexe palléal en position antéro-latérale, et se continuant par la progressive torsion spirale des viscères, du muscle columellaire et de la coquille [...]. Cette torsion non seulement affecte le sac viscéral et la coquille qui moule le manteau en leur imprimant une forme hélicoïdale, mais entraîne aussi le "chiasma" du système nerveux dont les ganglions, initialement placés à droite, vont prendre une position topographique gauche et "vice versa". Et surtout, la principale conséquence de la torsion hélicoïdale est d'avoir transformé les Gastéropodes en animaux dissymétriques: l'étude des parties molles prouve que les organes pairs du côté droit (côté gauche originel) sont plus petits que ceux du côté gauche, et peuvent même s'atrophier et disparaître.  2, fiche 2, Français, - torsion

When molluscs are dredged out from sea beds, some of the sand and silt swirled up during the operations may enter their mantle cavity. In such cases, the animals can be spread out on a cleansing plot or basin and covered with gently flowing sea water for varying periods of time. This helps them to eliminate any silt or sand and also recover from the fishing stress.  1, fiche 4, Anglais, - cleansing%20plot

White still a veliger, the young prosobranch gastropod undergoes a fundamental change in the orientation of its organs, which may be regarded as a combination of two movements. As a result of the first, known as the "anopedal flexure", the alimentary canal, instead of being aligned from front to rear, becomes bent so that the rectum points to the front and the anus discharges into the mantle cavity.  1, fiche 6, Anglais, - anopedal%20flexure
