Demersal species over sandy substrates in deeper water;
type series trawled at 42 m depth in the
southeast arm of Lake Malawi.
Geographic distribution:
Southeast arm of Lake Malawi; recorded from trawling
stations off Mazinzi and surrounding deep-water
sandy areas.
Typical adult size:
Medium-sized species reaching about
20 cm total length.
Sexual dimorphism:
Males larger than females and develop more intense
breeding coloration; both sexes share the
characteristic three-spot lateral pattern.
Diet:
Unknown; presumed benthic feeder associated with
sandy substrates.
Breeding:
Not documented; as with other Malawi
haplochromines, presumed maternal
mouthbrooder.
Special notes:
Distinguished from all congeners by its very elongate
body (depth 24.3–28.6% of standard length).
Lacks dorsal midline spots present in
O. lithobates. Formerly referred to as
Otopharynx “productus” or
O. sp. “torpedo blue” in the literature.
