Attributs

  • DISTRIBUTION: Lien Faunafri
  • Colour pattern : Eccles et al., 2011 .
  • Current distribution known : endemic to Lake Malawi and its associated lakes and lagoons. It is found in Mazini Bay and near Chembe in the south and in Sanga on the central-western shore of the lake .
  • Food habits / trophic level : feeds on ostracods, cladocerans, copepods, chironomid larvae and small trichopteran larvae; some diatom frustules were also observed but it is possible that these were taken fortuitously with invertebrate food items .
  • Habitat / home range : recorded from depths of 10-30 m in the southern part and at a depth of about 20 m at Sanga in the central portion of Lake Malawi. It is found in empty gastropod shells .
  • Morphology / anatomy : Eccles et al., 2011 .
  • Reproduction : both sexes attain maturity at a standard length of about 17 mm. Mature males take up territories in shells; females may share these for some time before depositing their eggs. Females leave the shells shortly after oviposition whereas the males remain in the shells, presumably to guard the brood; the small size of the buccal cavity and the narrow mouth with a width less than 2.5 egg diameters, suggests that mouth brooding is improbable .
