Consigli per l'identificazione

1. 1

   Body Rings

   Count the number of bony rings on the trunk and tail. This is a key taxonomic feature for distinguishing species.

2. 2

   Coronet Shape

   The coronet (crown-like structure on the head) varies significantly in height, shape, and number of spines among species.

3. 3

   Spines and Tubercles

   Examine the presence, size, and arrangement of spines and tubercles on the body, which can be species-specific.

4. 4

   Snout Length

   The relative length of the snout to the head can be a distinguishing characteristic.

5. 5

   Dorsal Fin Rays

   Counting the number of dorsal fin rays can aid in species identification, though this requires careful observation.
