Vastallosi river dolphin

The Vastallosi River Dolphin (Platanista essendae), known as "Boto" or "Golfinho de Rio" by the Mamaco tribe, is a species of dolphin that inhabits the rivers of the vastallosi jungle and coastal areas of Vastallos. They are important to the culture of the Mamaco tribe, being described as rare and elusive night hunters that maintains the balance in the rivers. The last photo of a river dolphin is from the 29th of august of 2021, being the last sighting made by Caiorod001. Due to their extremly rare sightings, the CBERO has put the species in the critically endangered-functionally extinct category.
== Distribuition ==
The historic distribution of the Vastallosi river dolphin reached as far as the coasts of Australiquia and all rivers of Vastallos, but usually only staying in coastal areas no more than 20 meters deep. But now is believed their only remaining pocket is in the northern coastal area.
== Ecology and behaviour ==
=== Ecology ===
The Vastallosi river dolphin is the apex predator of its river ecosystem, preying upon every kind of fish native to the area. By being such ferocious predator, the dolphin controls the population of animals in the river, and without them the river ecosytems have been showing negative signs such as overgrazing on aquatic plants that disrupts breeding areas of native fish, reducing their population. That is known as a trophic cascade.
=== Behaviour ===
They are mostly solitary throughout the year, but once a year they form a school of normally 20 dolphins and go breed in deep waters, and that is also a hint that maybe the species is functionally extinct because no one has seen a school in 4 years. After the 8 month long pregnancy the babies stay with their mothers for about 3 years, after that they will separate and the child will live on its own. 
They are known for being very shy and docile with humans, but are defensive of their young.
== Appearance ==
Although similar to the Bottlenose Dolphin (Turisops truncatus), they are smaller and have a more pink skin tone. Adults normally reach 1.2m in length and weigh about 35kg. They also have a rounded fin and small eyes, using echolocation to navigate the muddy rivers.
== Threats and extinction ==
The biggest threats to the dolphins are destruction of their habitat by overusing and building things on their rivers such as dams and overhunting and pollution. Caiorod001 was the last person to sight one and he thinks that he might have seen, the last vastallosi river dolphin in existence. Although they might still have a surviving population, they are considered functionally extinct due to low population numbers and low influence in their habitat.
