One of two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face, and form, by their junction, 'the bridge' of the nose[WP]. Paired dermal bones, likened to a bone tube, positioned lateral to the supraethmoid. Nasal bones are transversed by the anterior most part of the supraorbital canals and bear one neuromast foramen in zebrafish[ZFA].

taxon notes

In primitive bony fish and tetrapods, the nasal bones are the most anterior of a set of four paired bones forming the roof of the skull, being followed in sequence by the frontals, the parietals, and the postparietals. Their form in living species is highly variable, depending on the shape of the head, but they generally form the roof of the snout or beak, running from the nostrils to a position short of the orbits. In most animals, they are generally therefore proportionally larger than in humans or great apes, because of the shortened faces of the latter. Turtles, unusually, lack nasal bones, with the prefrontal bones of the orbit reaching all the way to the nostrils (ISBN 0-03-910284-X)
