Etymology: Diplotaxodon: Greek, diploos = twice + Greek, taxis = disposition + Greek, odous = teeth (Ref. 45335).
Environment / Climate / Range
Freshwater; pelagic; depth range 20 - 220 m (Ref. 94786). Tropical, preferred ?
Africa: Lake Malawi.
Length at first maturity / Size / Weight / Age
Maturity: Lm 14.5  range ? - ? cm
Max length : 15.4 cm SL male/unsexed; (Ref. 55949); max. published weight: 60.00 g (Ref. )
Diagnosis: more slender and elongate than congenerics, with smaller head, eyes and mouth; ripe males with yellow-white dorsal "blaze" (Ref. 55949).
Found inshore and offshore, on reefs and over the shelf; abundant over the anoxic zone; female mouthbrooder (Ref. 55949). Zooplanktivorous; probably the most abundant species in Lake Malawi (Ref. 94786).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Males in breeding dress were found throughout the year; ripe adults and mouthbrooding females were recorded at depths of 50-125m; largest fry found in the mouth of females were 3cm TL, but a maximum of only 1-2 such large fry were found per female; juveniles of 40-50mm were found in many locations (Ref. 55949).
