Description:
The specimen (USNM 265800) was collected 21 July 1980
off Nkhata Bay, Malawi by M.K. Oliver, K. McKaye,
and T. Kocher and was alive when I photographed it.
So far as I can determine, this is the only museum
specimen collected since the species was described
from three type specimens by Peter B.N. Jackson (1955).
The small, laterally placed eyes that bulge out from
the outline of the head, a key characteristic for
distinguishing Bathyclarias from Clarias,
can be seen in the close-up of the head at right.
B. foveolatus (called "Chimwamapumba"
locally) is piscivorous according to Jackson (1961),
who remarks that "it is probably sluggish in
habits, skulking among the rocks and mud at great
depths; it is invariably caught in the bottom few
meshes of deep-set gill nets. Of no economic importance
as many Africans refuse to eat it, fearing that smallpox
might be contracted from its pock-marked skin. (Michael
K. Oliver; malawicichlids.com). Habitat:
Occurs at a depth of 30m and deeper, (hence the genus
name) in rocky areas. Feeds on rock-inhabiting species
during the night. Prefers rocky substrates and feeds
exclusively on fish.Remarks:
The Bathyglanis genus contains 12 species
with the type of the genus Clarius longibarbus
Worthington, 1933. The species of the Dinotopterus
genera are very similar but are found in Lake Tanganyika.
