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).

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 21; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 24; Wirbelzahl: 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).
