Consigli per l'identificazione

1. 1

   Mouth structure

   The most defining feature is the fused teeth forming a parrot-like beak. This is distinct from other reef fish.

2. 2

   Coloration and pattern

   Observe the overall color scheme and specific patterns. Note if the fish is in an initial phase (often drabber, female or juvenile) or terminal phase (often brighter, male) as this significantly alters appearance. Look for specific markings on the head, body, and fins.

3. 3

   Body shape and size

   Parrotfish generally have robust, somewhat elongated bodies. Size varies greatly among species, from small species around 20 cm to large ones exceeding 1 meter.

4. 4

   Feeding behavior

   Watch for their characteristic scraping of coral or rock surfaces, leaving visible bite marks. This behavior is unique to parrotfish among common reef fish.
