   Look for the presence and size of the adipose fin, which is typically large and distinct in Synodontis.

2. 2

   Barbels

   Count the three pairs of barbels and note their length and any branching (e.g., mandibular barbels can be branched in some species).

3. 3

   Fin Spines

   Observe the strong, serrated spines in the dorsal and pectoral fins, a characteristic of the Mochokidae family.
