| One of the most noticeable characteristics of most trenches is their arcuate plan, convex toward the subducting plate. |
| Leaves alternate or less often opposite or verticillate, with parallel or arcuate venation, usually with vaginate base. |
| Flexures provide quasilinear translation without stiction and friction, but flexure-based-translational motion is inherently arcuate. |
| Markings on the shell consist of prominent growth lines in an arcuate or concentric pattern. |
| Tidal-estuarine, arcuate, cuspate, lobate, and birdfoot deltas have been mentioned in the literature. |
