Figure 4

Sagittal otoliths from mature Schindleria specimens sampled with light traps from an inshore (A), a mid-shelf (B), and a shelf-edge (C) reef in the Red Sea, near the coast of Thuwal, Saudi Arabia. These otoliths represent otoliths of ideal conditions (i.e., “C3” category) to count daily growth increments and yielded similar average numbers of increments (between 26 and 28) despite slightly differing shapes and sizes. All otoliths are to scale, with the bar at the bottom (left) of each panel representing 20 μm. The otolith at the top of each panel represents a rounder and larger otolith while the otolith at the bottom a more oval-shaped and smaller otolith.
