dorsal fin
- Short fin with darker grey to brownish colour.
- Low angular leading edge
- Strongly convexed (curving outwards) trailing edge.
- A short free rear tip.
Note: Looks similar to Silky dorsal fin (CITES-listed). The silky dorsal has a longer free rear tip and a steeper slope on the leading edge. It also has a smoother texture and a more uniform grey color.
