- In ornithology, cutting, as a part of the bill; of or pertaining to the tomia, or to a tomium: as, the tomial edge of the bill; tomial serration.
Sorry, no etymologies found.
Anastomus, the Open-billed stork, has scopate tomial edges (meaning that it possesses tiny brush-like structures along the margins of its bill) and upper and lower jaws that bow away from each other, meaning that their edges never meet.
Falcons use a notched ridge on their upper beak - the 'tomial tooth' - to sever the spine or crush the head, while owls sometimes break their prey's neck with a swift twist.
