Current distribution known : known only from the Bushmans, Kariega, Kasouga, and East and West Kleinemonde estuaries on the Eastern Cape coast of South Africa .
Ecology : Whitfield et al., 2017 .
Food habits / trophic level : feeds almost exclusively on zooplankton .
Genetics : Mwale et al., 2013 .
Habitat / home range : occurs in rivers with tidal influence. Found in association with submerged aquatic macrophytes, primarily the eelgrass Zostera capensis .
Morphology / anatomy : Mwale et al., 2013 .
Phylogeny : Mwale et al., 2013 .
Reproduction : the species is ovoviviparous, and the male carries the eggs in a brood pouch which is found under the tail. Sexual maturity is attained at approximately 10 cm standard length with males retaining up to 44 embryos. 28: The presence of breeding individuals and juveniles indicated that the spawning period of the species occurs in spring and summer, coinciding with warmer water temperatures and enhanced food resources, with reproductive activity peaking. The mean number of mature oocytes in the females is about 270-486 .
