Teleostei (teleosts) >
Cypriniformes (Carps) >
Nemacheilidae (Brook loaches)
Etymology: Schistura: Greek, schizein = to divide + Greek, oura = tail; an allusion to forked caudal fins (Ref. 45335); oedipus: Specific epithet means a mythic Theban King who tore out his eyes (Ref. 39226).
Eponymy: This is not a true eponym as Oedipus was a mythical Theban king who tore out his eyes (after discovering that the woman he married was his own mother). The binomial is here used in fanciful reference to the loach’s degenerate eyes. (Ref. 128868), visit book page.

Freshwater; benthopelagic; depth range 0 - ? m (Ref. 42927). Tropical; 20°N - 19°N

Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 5.4 cm SL male/unsexed; (Ref. 39226)
Dorsal soft rays (total): 12; Anal soft rays: 8. No color pattern; absence of externally visible eye but a pit in the center of the skin covering the orbit (Ref. 39226). Retains some melanin pigmentation (Ref. 42927).
Cave-restricted species (Ref. 12041). Collected in a pool of moving water about 1 km from a cave entrance (Ref. 39226). Mostly found stationary on the muddy bottom at depths from 20 cm to 1 m (Ref. 42927). Tends to occur in slow moving water during the dry season, but some individuals were observed climbing rapids (Ref. 42927). Small groups of individuals were frequently found in the pools while isolated individuals were common in rapids (Ref. 42927). Weakly or not at all cryptobiotic, not remaining under rocks for more than 5 min during the day (Ref. 42927). Feeds on insects and roundworms (Ref. 42927). Shows behavioral responses to light, including avoidance and perhaps a residual diurnal rhythmicity (Ref. 42927).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00310 - 0.01545), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 3.1 ±0.34 se; based on food items.
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).
