North American river dolphin (SciiFii)

The North American river dolphin (Alexadelphinus sacramentoensis), also known as the northern river dolphin, the North American boto, and the brown river dolphin, is a species of river dolphin of the family Iniidae, most closely related to the Amazon river dolphin (Inia geoffrensis), that originally did not exist, but has since been created by SciiFii and introduced throughout the lakes, rivers, and estuaries across North America to help boost biodiversity. The North American river dolphin is one of the largest species of river dolphin, along with the Amazon river dolphin, with adult males reaching 185 kilograms (408 lb) in weight, and 2.5 metres (8.2 feet) in length. Adults are primarily brown in color, with males being more brighter brown than the more greyish-brown females, giving it its nickname "brown river dolphin". Sexual dimorphism is very evident, with males measuring 16% longer and weighing 55% more than females. Like other toothed whales, they have a melon, an organ that is used for bio sonar. The dorsal fin, although short in height, is regarded as long, and the pectoral fins are also large. The fin size, unfused vertebrae, and its relative size allow for improved manoeuvrability when navigating flooded forests and enlarged lakes/rivers, as well as while capturing prey. The North American river dolphins have one of the widest ranging diets among toothed whales, and feed on up to 129 different species of fish, such as bass, gobies, carp, catfish, trout, and salmon. They also consume other animals such as pond/river turtles and freshwater crabs. The conservation status of the North American river dolphin is Least Concern due to successful conservation efforts, the North American river dolphin's wide range and, unlike most other river dolphins, its tolerance to many of the human activities.
