1.Aloidis (Corbula) gibbais a eulamellibranch specialized for life in muddy gravel substrata to depths of up to about 80 fathoms.2. The shell is asymmetrical, the margin of the smaller, left valve being uncalcified and so fitting within the marginal region of the right valve. A possible manner in which this asymmetry is produced by the differential secretory activities of the two mantle edges is discussed.3. The marginal periostracum of the left valve has strengthening calcined regions posteriorly, probably to protect the siphons when extruded.4. The external ligament is reduced and the resilium condensed, possibly permitting some antero-posterior rocking of the shell valves when the adductors contract.5. The process of burrowing is described; on its completion the animal is anchored by a single byssus thread.6. The siphons are very short, the tentacles of the siphonal sheath lying on the surface of the substratum. The inhalant siphon is wide and relatively insensitive; it draws in much bottom material. The exhalant siphon is tubular and very sensitive. It is controlled by two paired bands of muscle.7. The great quantities of pseudo-faeces which accumulate are expelled by periodical contractions of the 'quick' portions of the adductor muscles, the asymmetry of the shell valves causing great reduction in the size of the inhalant chamber. The foot may also assist in clearing the chamber. 8. The large ctenidia create a very powerful current; they are adapted for dealing with large amounts of sediment by means of specialized terminal, guarding and cirrus-like cilia. Control of 'pumping' is primarily by means of the exhalant siphon.9. The stomach is large in correlation with the great amounts of inorganic material carried in with the food.

论Aloidis (Corbula) Gibba的习性与适应

1.Aloidis (Corbula) gibba是一种 eulamellibranch，专门生活在泥泞的砾石基质中，深度可达约 80 英寻。2。壳是不对称的，较小的左侧瓣膜的边缘未钙化，因此适合右侧瓣膜的边缘区域。讨论了两种地幔边缘不同分泌活动产生这种不对称性的可能方式。 3．左瓣膜边缘有后部的强化煅烧区，可能是为了保护虹吸管被挤压。 4．当内收肌收缩时，外韧带减少，弹性体收缩，可能允许壳瓣的一些前后摇摆。 5．描述了挖洞的过程；在其完成时，动物由单个 byssus thread.6 锚定。虹吸管很短，虹吸鞘的触手位于底层表面。吸入式虹吸管较宽且相对不敏感；它吸收了很多底部材料。呼出的虹吸管是管状的，非常敏感。它由两对肌肉带控制。7。大量堆积的假粪便通过内收肌的“快速”部分的周期性收缩排出，壳瓣的不对称导致吸入室的尺寸大大减小。脚还可以帮助清理腔室。8. 大栉叶产生非常强大的电流；它们适用于通过专门的末端、防护和卷云状纤毛处理大量沉积物。“泵送”的控制主要是通过呼气虹吸管。9。
