Salmo salar (Linneaus 1758; up to 1m) is the extant Atlantic salmon. The toothy premaxilla extends horizontally while the dentary curls dorsally, leaving the mouth open permanently. The nares appear at a gap between the premaxilla and nasals. The young hatch in fresh water, then swim out to sea.
Coloring the bones
to match tetrapod bones helps to quickly and confidently make comparisons. Fusion can be noted without adding sutures. Missing bones can be added without creating confusion.
