The dageraad has an orange head and body which is white below with a dark front of head and black rear margin. There is a blue line below the eye in adults and a black spot at the base of the last 3 dorsal rays. Juveniles are pink with a horizontal mid lateral line band, two dark blotches below the dorsal fin and a black spot at the rare of the dorsal base. The body depth is greater that the head length and is 2 – 2.3 times SL. There are 12 dorsal spines and 10 rays and 8 anal fin arrays. The dageraad’s pectoral fins are longer than the head and have 16 rays. The tail is forked with rounded lobes in adult fish. The jaws have 4-6 slender canines and 3 or more series of small molars behind. 59-61 lateral line scales and scaly inter-orbital area, pre opercula margin and bases of soft dorsal and anal fins (Heemstra and Heemstra 2004).
The dageraad is endemic to South Africa and is only found from Cape Point to Durban in KwaZulu-Natal (Fischer and Bianchi 1984, Smith and Heemstra 1986, van der Elst 1988). A few larger specimens have been recorded as far North as Richards Bay in KwaZulu-Natal (P. Garratt pers. comm. 2009).
As above.
Dageraad are resident species but there may be some nomadic movement between reefs (Buxton and Allen 1989, Buxton and Smale 1989, Griffiths and Wilke 2002, ORI Tagging Project, unpubl. data).
Adult dageraads are carnivorous feeding on benthic invertebrates associated with reefs (Buxton 1988). Juveniles follow the same feeding traits as adults however just eat smaller prey (Buxton 1988).
Dageraads are protogynous hermaphrodites with sex change occurring when they reach a length of around 43.5cm FL (Buxton 1988, 1989, 1990).They spawn from October to January (Buxton 1990) on reefs in the eastern Cape (Buxton 1990). They produce small pelagic eggs with a large oil droplet (Buxton 1990). Dageraads reach maturity when females are 7.7 years old and males are 11 (Buxton 1990). At these ages they are usually 27.5-36.5cm FL and 43.5 mm respectively (Buxton 1990).

Dageraads are an important species in both the commercial and recreational skiboat linefisheries in the Eastern Cape and Western Cape (Crawford and Crous 1982, Smale and Buxton 1985, Hecht and Tilney 1989, Brouwer and Buxton 2002). The decline in numbers has reduced its importance in the commercial linefishery (Donovan 2010). Dageraads are also occasionally taken by spearfishers capable of diving on deeper reefs below 20 m depth (B. Mann, ORI, pers. obs.).
