|Type Locality||Lake Malawi [Lake Nyasa], southeastern Africa.|
|Synonym(s)||Clarias nyasensis, Dinotopterus nyasensis|
|Pronunciation||bath ee klar ee ass.|
|Etymology||From the Greek bathys meaning deep and clarias also from the Greek chlaros, meaning lively; in reference to the ability of clarias to live for long periods out of water.|
|Size||1000mm or 39.4" SL. Find near, nearer or same sized spp.|
|Identification||The small, laterally placed eyes that bulge out from the outline of the head is a key characteristic for distinguishing Bathyclarias from Clarias.
B. nyasensis can be distinguished from the other species of Bathyclarias by having all of the following characters (adapted from Greenwood, 1961: 230):
1. Gill rakers long, length of longest gill raker (on outer arch) divided by length of longest gill filament = 0.7-1.0;
2. Body relatively slender;
3. Maxillary barbel contained 1.8-2.2 times in head length.
|Sexing||The genital papilla, which is to the right of the anus as you look at the fish with its head to the left, is elongated and pointed in males while it is round and relatively larger (and larger than the anus) in females. In ventral view especially, females are much broader in the body than males of equal age and rearing practices.|
