Etymology: Mystus: Greek, mystax = whiskered, used by Belon in 1553 to describe all fishes with whiskers (Ref. 45335); keralai: The specific name refers to Kerala, the state of India from which the new species was described firstly..
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
Asia: Manimala River in Kerala, India.

Max length : 5.9 cm SL male/unsexed; (Ref. 96965)
Morphology | Morphometrics
soft rays: 13. Distinguished from its relatives by its elongated, wider but less deep head, smaller eyes, deeper anterior part of frontal groove, longer base of adipose dorsal fin, elongated pelvic fin, anal fin and pectoral spine, weaker pectoral spine and longer base of rayed dorsal fin base. Can be further diagnosed from other species of Mystus by the possession of very long maxillary barbels which reach beyond caudal base, a distinct mid lateral stripe and elongated humeral spot and triangular caudal spot (Ref. 96965).
Facultative air-breathing in the genus (Ref. 126274); The river stretch of the type locality is highly sinuous, generally rocky with deep pools at certain locations and has bed materials generally of coarser grade and of very low sand content. The pools have sporadic patches or fillings of sand deposits (Ref. 96965).

= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00484 - 0.02371), b=2.96 (2.78 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
