Protosphyraena (SciiFii)

The Cretaceous swordfish (Protosphyraena gladius), also known as the Mesozoic swordfish, is a species of swordfish-like marine fish of the family Pachycormidae that originally lived throughout the world's oceans during the Upper Cretaceous Period (Coniacian-Maastrichtian) as an extinct species of Protosphyraena and was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern world's oceans to help boost biodiversity. The Cretaceous swordfish is a large fish, averaging 2–3 metres in length, although some Cretaceous swordfish can grow slightly larger to about 3.5 meters in length. In its general body plan, it resembles a sailfish and a true swordfish, though it is smaller with a shorter rostrum, is somewhat less hydrodynamic, and adults possesses large blade-like teeth (adults of true swordfish species are toothless). The Cretaceous swordfish is a carnivore that is known for being steady at cruising and it primarily feeds on any squid, ammonite, crustaceans, and fish smaller than itself, although it can occasionally also feed on carrion to supplement its diet, filling the niche similar to both swordfishes and scavenging sharks. The conservation status of the Cretaceous swordfish is Least Concern due to successful conservation efforts, the Cretaceous swordfish's wide range and its tolerance to many of the human activities.
