The mouth is slightly oblique and reaches back beyond the large eye, which in turn has a diemeter of nearly four times the length of the head.

[2][3] Jaydia queketti occurs in the western Indian Ocean from the Red Sea south to KwaZulu Natal, east to the Persian Gulf and India.

[5] Jaydia queketti is a nocturnal species which emerges into the water column at night to feed on zooplankton, hence the large eye, close to the substrate to a depth of 90m.

[3] Jaydia queketti was named in 1903 by the Scottish ichthyologist John Dow Fisher Gilchrist as a species in the genus Apogon.

[6][7] Gilchrist did not specify who the specific name honours but it is thought to most likely be the conchologist John Frederick Whitlie Quekett (1849-1913) who was a curator of the Durban Natural History Museum.
