While ungainly on land, the stocky, blubbery squalruses are perfectly suited to life at sea, and they are equally at home in both the waters of the frigid poles and the tropical coasts. They reach lengths of 12'-15' long, and can weigh between 1 and 2 tons.
Squalruses hunt in organized packs, using rows of razor-sharp teeth and piercing tusks to bring down prey...and their highly-developed minds make them even more dangerous. They have been known to attack water vessels.
Unlike most mammals, squalruses lay small clutches of 1d6 eggs. These eggs are highly prized amongst coastal and seafaring tribes, as hatchlings can be trained to serve as loyal guards, hunting companions, and trackers.
