Feliforms tend to have shorter rostrums (snouts) than caniforms, fewer teeth, and more specialized carnassials. Some fish have permanently protruding upper jawbones called rostrums. Sclerorhynchoidei is an extinct suborder of sclerorhynchiform rays with saw-like rostrums. Their bodies are golden-red in color, with their rostrums and legs brown. On average, females have shorter rostrums with fewer teeth than males. The rostrums extend ventrally in front of the fish. The two genera both have large preoccipital processes, similar cranium shapes, and short rostrums. Their small furred ears are well-rounded and their rostrums are short. Oviraptorosaurians have shortened rostrums, massive, beaklike mandibles, and long parietal bones. Billfish (marlin, swordfish and sailfish) use rostrums (bills) to slash and stun prey. Their rostrums are slightly longer than the species "L.flavopunctatus". Paddlefish have elongated rostrums containing electroreceptors that can detect weak electrical fields.
