Herring Cale

​Herring Cale have a long, cylindrical body shape allowing them to swim in an eel-like manner. Their mouth is shaped for grazing seaweeds with fused teeth in both upper and lower jaws, giving a beak-like appearance. Males range in colour from pale blue to pale blue to nearly black. They have bright blue lines on their tail and pectoral fins, and across the snout. Females are mostly brown, darker on top. They have thin blue wavy lines on their head, with pale spots on their scales. Their fins also show faint blue patterns. Juveniles tend to be grey or brown on top and yellow underneath. They have dark blotches and a faint, broken stripe along their sides.
