Name of the model: Tumaricone Conch OrnamentedTriangles: 1216312Vertices: 608156Information: This model emulates an almost spherocone to cadicone conch known astumaricone, with an ornamented shell surface (ribs and nodes). According to Westermann (1996)Spherocone shells are overall inflated, and may be wider than the planispiral diameter.Spherocones have most or all of the umbilicus covered. Locomotion would be optimized at lowspeeds (Jacobs 1992). At very small sizes, such as hatching size, viscosity ensures laminar flow,and a lower friction drag makes the sphaerocone more efficient than compressed forms (Jacobs1992).References:Jacobs DK. 1992.
