| Bathymargarites symplector Warén & Bouchet, 1989. Family Trochidae (Warén & Bouchet, 2001). | |
See also Warén & Bouchet, 1993 for details of the larval shell.
Larva also pictured in Desbruyères et al. (2006) p. 101.
| Size under dissecting microscope: ~350µm Size under compound microscope: ~320µm |
| Morphology: The shell consists of two parts, a proximal smooth portion approximately 200μm in diameter and a distal portion with axial striations. The aperture is curved, flares out at the anterior edge and is asymmetrical, extending farther out on the apical side than on the basal side. |
| Frequency: Pump EPR 1999-2000: Rare Pump EPR 2004: Rare Trap EPR 2004-2005: Frequent |

Bathymargarites' larval shell is unique among the species at 9°N and is therefore not likely to be confused with any other species. It has a superficial similarity to Melanodrymia aurantiaca, shown at left, but the latter is much smaller (~260μm) and has reticulate sculpture over the entire shell. |
