Longirostris Synodontis Catfish
In the genus Synodontis, all species share common anatomical features. They possess a hardened head cap with an attached process called the humeral process, which is located behind the gill opening and points towards the posterior. The first ray of the dorsal fin and pectoral fins is also hardened and serrated. The caudal fin is always forked in shape. They have a pair of maxillary barbels, which may sometimes have membranes and occasionally be branched. The two pairs of mandibular barbels are often branched and may have nodes attached. The teeth in the upper jaw are cone-shaped and short, while those in the lower jaw are S-shaped and movable.
An interesting characteristic of these fish is their ability to produce audible sounds when disturbed. This sound is generated by rubbing the base of the pectoral spine against the pectoral girdle, creating a unique acoustic signal.
