Etymology: Perissodus: Greek, perissos = uneven + Greek, odous = teeth (Ref. 45335).
Environment / Climate / Range
Ecology
Freshwater; pelagic. Tropical, preferred ?; 3°S - 9°S
Africa: endemic to Lake Tanganyika, occurs in the southern half of the lake (Ref. 46829, 93918). One juvenile was collected on the western coast of the lake, near Kalemie (Ref. 93918).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 16.4 cm SL male/unsexed; (Ref. 5678)
Pelagic species (Ref. 6770) occuring in the rocky habitat (Ref. 46829). Scale-ripper (Ref. 6770, 46829). Caught at depths from 60-100 metres (Ref. 93918), but has also been seen in the shallow rocky habitat (Ref. 46829). Breeding behaviour is interesting as it involves a pair bond even though they are mouthbrooders in which the female broods the eggs (Ref. 466829). Come to shoreline to release their fry (Ref. 6770).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic Level (Ref.
69278): 4.4 ±0.80 se; Based on food items.
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (23 of 100) .
