Etymology
Halichoeres: from Greek, halio-, hali-, halo-, hal- = word-forming element meaning "salt, sea," a Greek combination form of hals (genitive halos) "a lump of salt, salt generally," in Homer, "the sea," + from Greek, choiros = pig. Referring to elongated conical tooth at each corner of mouth, pointed outwards and forwards, and usually protruding beyond the flesh of lips, which reminded Rüppell of the canine teeth of a boar; Here "hog of the sea or hogfish".
margaritaceus: from Greek, margarites = a pearl + from Latin suffix, -aceus = of or pertaining to. Referring to pearly white blotches on lower sides of intermediate-phase females; Valenciennes also mentioned a pearly white line under the eye.
