Remucauda occisorostrus

From OurFoodChain

This descendant of Remucauda subsalis has evolved itself into a carnivorous niche, without much competition in its environment. Remucauda occisorostrus uses its "toothy" beak to feed on Sturgoslontus sturgensis, Sturgoslontus sturgenousis, Sturgoslontus sturgenmacrops, Sturgoslontus opscuruclavis, and their descendants. They do not feed on other members of the genus Remucauda as they pose a high risk with their beaks and they will not typically feed on polyphs unless desparate or incapable of hunting as polyphs take more effort to digest and so that they do not complete with primary consumers for food. It grows to twenty-five centimeters (25 cm) in length to help eat the smaller creatures.

Remucauda occisorostrus has a slightly elongated beak outwards as opposed to the beaks of its relatives as it helps to catch prey more easily. The beak on the upper jaw has a triangular formation on the bottom which points downwards. This increases the pressure inflicted onto the soft bodies of its prey when they are bitten down on. The "teeth" also help to tear prey items where they are bitten, making its bites more deadly. In fact, the specific name means "killer beak."

Remucauda occisorostrus is tinted blue which helps it with camouflage. Its back is darker in color than its stomach, an example of countershading. The darker colors are uneven in pattern on some spots, making it harder to see from a distance.


Adults will cruise casually near the surface of the water until they spot what they believe to be a prey item, which they will charge towards and bite to kill before eating. Younger specimens smaller than the prey will feed on scraps of meat and detritus (including polyphs) until they are large enough to hunt. They will test hunting on younger versions of their prey before trying adults.

Remucauda occisorostrus matures at ten (10) weeks of age and reproduce on the shoreline like their ancestor, but fifty-five (55) meters away to avoid interspecific competition. Females lay their eggs at the lower range of fifteen (15) as to not over-consume their prey sources, and adults have little to no predators. Young may be fed on by Sturgoslontus sturgenmacrops when they are under ten (10) centimeters in length. Their mating cycles sync up every ten (10) weeks. When it gets colder, Remucauda occisorostrus will hibernate away from the shoreline forty to fifty meters (40-50 m) to conserve energy until they become active in the spring again.
