Sea wolf (SciiFii)

The sea wolf (Liophitygex proto), also known as the sea dog, is a species of fully-aquatic canid that originally did not exist, but has since been created by SciiFii and introduced throughout the subtropical and temperate oceans off the coast of the Azores archipelago to help boost biodiversity. It is most closely related to the Vancouver Island wolf (Canis lupus crassodon), and is the most likely animal used for creating the sea wolf, being modified to be totally adapted to life in the ocean. It is a large animal, growing to be about twice the size of a killer whale (Orcinus orca). It is a carnivore, like its closest relative, feeding primarily on fish, cephalopods, crustaceans, sea turtles, pinnipeds, whales, desmostylids, and among other animals smaller than itself. Although it primarily feeds on fully-aquatic animals, it can also hunt amphibious and/or fully-terrestrial land animals that get too close to the sea shore, and it can pull any amphibious/fully-terrestrial land animal into the water to drown it. It vagely resembles an outdated pre-2015 pliosaur, with its short paddleless tail, four flippered limbs, a barrel-shaped body, and an elongated crocodile-like head filled with large, strong, and sharp teeth. Like the plesiosaurs, it can swim by paddling with its four flippers two at a time, ones on the front and the others back. The sea wolf is a solitary animal in most of its life except during the breeding seasons. The conservation status of the sea wolf is Least Concern due to successful conservation efforts and the sea wolf's wide range.
