Teleostei (teleosts) > Osteoglossiformes (Bony tongues) > Mormyridae (Elephantfishes)
Etymology: Cryptomyrus: Name from the Greek ‘kryptos’ for secret or hidden, referring to the rarity of these fishes in collections and the Greek ‘myros’ for a kind of fish, a suffix used in the names of many other mormyrid genera.;  ona: The specific epithet is a noun in apposition that honors Marc Ona Essangui, Gabonese environmental and civic activist, founder and executive director of the NGO Brainforest and recipient of the 2009 Goldman Environmental Prize, in appreciation for his efforts to protect Gabon's equatorial forests and wetlands (Ref. 113668).

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 10.8 cm SL male/unsexed; (Ref. 113668)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 21; Anal spines: 0; Anal soft rays: 24; Vertebrae: 41. Diagnosis: Cryptomyrus ona is readily differentiated from its sole congener, C. ogoouensis, by the following characteristics: having an anal-fin origin located only just in advance of the dorsal fin, first dorsal ray above anal-fin ray 3 vs. first dorsal-fin ray above anal-fin ray 7; a deep caudal peduncle, 6.0-6.8% of standard length vs. 5.1%; and lobes of caudal fin markedly shorter than caudal peduncle, vs. nearly as long as peduncle (Ref. 113668).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00251 - 0.01261), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.3 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).
