Appearance
The Christmas wrasse has 8 spines and 13 soft rays in its dorsal fin and 3 spines and 11 soft rays in its anal fin. There are normally 16 rays in the pectoral fins and there are 25 scales in the lateral line. In the initial phase, or females, the caudal fin may be slightly rounded or truncate while in the terminal phase males it can be truncate or a little double emarginated. The females are greenish grey to pale green in body colour with 5–6 dark blotches on the back and a pair of dark, not all that well defined stripes on the flank. Most of the scales on a female's body have a dark vertical line. There is also a diagonal or C-shaped pink to dark red marking below the front of the eye.
