Photographs of the male Madagascar wrasse, Macropharyngodon vivienae.

This species was first described from Madagascar but is now also  known from Aliwal Shoal to Ponta Malongane in southern Mozambique.  The Aliwal record is a range extension from Durban and is based on a female that was caught during a  Fish-Watch collecting dive.


M. vivienae, female, 53 mm.

During a Fish-Watch dive on the Pinnacles at Aliwal in August, 1999, Phil and Elaine Heemstra saw a wrasse swimming close to the reef and agreed that it must be a male Madagascar wrasse. The male vivienae colour pattern has been described, but as far as we know there are no published photographs of it.  The female vivienae is shown above.  Note the black ocellus (eye-like spot) with its bluish border just above and behind the gill opening.

The basic body colour of the adult male is the same, but the blue border of the ocellus  breaks up, increases in area, and looks as though it has curdled into the black area.  Males are also supposed to have two large oval dark red spots at the base of the  caudal fin, but we didn’t remember that at the time,  and never noticed them.

If you are a photographer, and are diving on  the Pinnacles (or anywhere in South  Africa), please look out for the male Madagascar wrasse.  We desperately need a photo for Elaine’s painting to illustrate the sexual dimorphism of this species for our forthcoming book on Western Indian Ocean fishes.
