Etymology: Sedercypris: Endemic to and named for the Sederberg (Cedarberg), Western Cape, South Africa, a Cape Fold mountain range in which rise streams and rivers tributary to the Olifants River system; the Afrikaans spelling of Sederberg is adopted for the name to avoid the possible confusion with the genus Cheilobarbus when the genus name is abbreviated to an initial in text..

Maturity: Lm ?  range ? - ? cm
Max length : 9.5 cm SL male/unsexed; (Ref. 2801)

Biology     Glossary (e.g. epibenthic)

Inhabits pools and deeper flowing stretches, forming schools of similar sized individuals. Juveniles sometimes in mixed schools with the Cape galaxias. Feeds on aquatic and other insects from surface and midwater. Breeds during summer, males congregating over bottom in flowing water. Threatened by water extraction, agricultural pollution and introduced fishes (Ref. 7248).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.40 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).
