Etymology: pellucida: From the Latin "pellucidus" (translucent, transparent), referring to the translucent body in live individuals of this "glass catfish" (Ref. 43912).

Morphology | Morphometrics
soft rays: 60 - 78;
Vertebrae: 44 - 50. Diagnosis: dorsal fin absent; adipose fin always present; inner side of pectoral-fin spine variably denticulate, with small to rather well developed serrations; 60-78 soft rays in anal fin (Ref. 43912, 57127, 81643). Vomerine teeth present (Ref. 43912, 81643). In general no small dark blotch at the base of the caudal fin (Ref. 81643).
Gregarious schooling species confined to larger lakes and rivers (Ref. 43912). Benthic species, occurs in deep water (Ref. 13851). Feeds mainly on small planktonic and benthic insects and crustaceans (Ref. 13851, 43912). Oviparous, eggs are unguarded (Ref. 205). Rarely exceeds 15 cm TL (Ref. 43912). Usually smoked or sun-dried, after which they are very tasty and may fetch high prices; sometimes ground into fish flour or fish meal and stored for long periods in sealed containers as an insurance against famine (Ref. 43912).

Phylogenetic diversity index (Ref. 82804
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00335 - 0.00945), b=3.12 (2.97 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.47 se; based on food items.
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
