Kyphosus cornelii
Western buffalo bream | Cornel's Drummer | Western Drummer
Distribution
Localised, Temperate Australasia
Description
More slender body shape than other drummers, inside of pectoral fins orange/yellow and light-edged upper and lower tail margins with dusky bar inside. It occurs in mixed schools with the silver drummer on the west coast. It differs from the silver drummer in having a more forked tail, and lacks the black edge to the tail fin and the moustache-like marking under the eye. Although both species feed predominantly on seaweeds, the diets of the two species differ, the western buffalo bream eating mainly red algae and the silver drummer preferring brown algae.

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Widespread (63.2% of sites)
Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
Abundance: Many (19 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
