   Nostrils

   Observe the number of nostrils on each side of the head. Cichlids typically have only one, while most other fish have two.

   While not externally visible, the presence of a well-developed pharyngeal jaw apparatus is a key internal anatomical feature. In live specimens, observe feeding behavior for specialized processing of food.

3. 3

   Lateral Line

   Examine the lateral line; in many cichlids, it is interrupted or divided into two distinct segments.

4. 4

   Fin Structure

   Note the single, often long dorsal fin with both spiny and soft rays, and the thoracic position of the pelvic fins.
