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".
biocellatus: from Latin, bis = two or twice + from Latin, occelatus = having small eyes or an eyelike marking in the form of a spot or ring of color, as on the wing of a butterfly or the tail of a peacock. Referring to pair of ocellate black spots on dorsal fin of juveniles and females.
