Max Poll Révision
des Synodontis Africains (Famille Mochocidae) (3)
Like all members of the genus Synodontis,
S. serratus has a strong, bony head capsule that extends
back as far as the first spine of the dorsal fin.
The head contains a distinct narrow, bony, external
protrusion called a humeral process. The shape and
size of the humeral process helps to identify the
species. In S. serratus, the humeral process
is rough, much longer than it is broad, and pointed
at the end. The maxillary barbels have a very broad
membrane and the mandibular barbels are branched.
All members of Syndontis
have a structure called a premaxillary toothpad, which
is located on the very front of the upper jaw of the
mouth. This structure contains several rows of short,
chisel-shaped teeth. In S. serratus, the
toothpad forms a short, broad band. On the lower jaw,
or mandible, the teeth of Synodontis are
attached to flexible, stalk-like structures and described
as "s-shaped" or "hooked". The
number of teeth on the mandible is used to differentiate
between species; in S. serratus, there are
about 30 to 45 teeth on the mandible. Aquarium
Care: As this species grows quite large it
is not really a candidate for aquarium keeping. Etymology:
The dorsal fin spine is finely serrated anteriorly
hence the specific name of serratus. Remarks:
Probably never been imported due to its initial large
basin. Type Locality: Cairo, Egypt.
Also found in Lake Albert.
