Etymology: Coelotilapia: "The genus name Coelotilapia Mayland, 1995 was introduced in a popular aquarium book, but it is not available, because it was treated as a questionable new genus, but was described as a generic name under Tilapia and not used in the combination Coelotilapia joka. The name was chosen to refer to the cave-breeding habit, but Mayland refers to the Latin word coelestis, which mean celestial. Very likely he thought of the Greek word ‘koiloma’, which means cavity.".
Eponymy: Joris Thys van den Audenaerde is the describer’s son. We assume that ‘Joka’ is a nickname, as the etymology says: “dedicated to my young son Joris.” (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
