FIGURE 4 in The larval, juvenile, and adult stages of the Caribbean goby, Coryphopterus kuna (Teleostei: Gobiidae): a reef fish with a pelagic larval duration longer than the post-settlement lifespan

FIGURE 4. Sagittal otolith of a 15.3 mm SL Coryphopterus kuna: the dark rod-shaped primordium is at far left, surrounded by the prehatching core (white oval), then followed by wide larval increments, sharply narrowing before the settlement transition (white arrow); the edge of the otolith is at far right; length of arrow=30 microns.
