The '''Amazon river dolphin (Inia geoffrensis)''', also known as the '''boto''' (pronounced 'boatoo'), '''bufeo''', or '''pink river dolphin''', is a species of [[toothed whale]] endemic to South America. These [[Dolphin|dolphins]] are known for their distinctive pink coloration, which is more prominent in males.
The '''Amazon river dolphin (Inia geoffrensis)''', also known as the '''boto''' (pronounced 'boatoo'), '''bufeo''', or '''pink river dolphin''', is a species of dolphin native to the freshwater rivers of South America, particularly the Amazon and Orinoco river basins. They are characterised by their distinctive pink coloration, which is more pronounced in adults and often fades with age. Pink dolphins have a flexible neck and long snout, which allows them to navigate through the flooded forests and shallow waters of their habitat. They are known for their intelligence and social behavior, often living in groups called pods. The Amazon river dolphin face threats from habitat loss, pollution, and fisheries, which have led to declines in their populations in some areas.


It’s the largest species of [[river dolphin]], with adult males reaching up to 160 kilograms (353 lb) and 2.55 metres (8.36 ft) in length and adult females reaching 1.96m(6.43 ft) in length and 96.5kg (213 lb).<ref name=":0">[https://portals.iucn.org/library/sites/library/files/documents/RD-1991-001.pdf Dolphins, Porpoises and Whales of the World - The IUCN Red Data Book] IUCN Pages (52-59)</ref>
== Physical description ==
 
# '''Color''': Amazon river dolphins are most commonly associated with a pink hue, though they can range from gray to pinkish-gray. This pink coloration is more prominent in adults and tends to fade with age.
# '''Size''': It’s the largest species of [[river dolphin]], with adult males reaching up to 160 kilograms (353 lb) and 2.55 metres (8.36 ft) in length and adult females reaching 1.96m(6.43 ft) in length and 96.5kg (213 lb).<ref name=":0">[https://portals.iucn.org/library/sites/library/files/documents/RD-1991-001.pdf Dolphins, Porpoises and Whales of the World - The IUCN Red Data Book] IUCN Pages (52-59)</ref>
# '''Body Shape''': Their bodies are robust and streamlined, with a long snout and a distinctive bulbous forehead, known as a melon. This shape aids in echolocation, which they use to navigate murky waters and locate prey.
# '''Fins and Flippers''': Amazon river dolphins have long, paddle-shaped pectoral fins (flippers) that they use for steering and maneuvering. Their dorsal fin is relatively small and triangular in shape. Their tail fluke is large and powerful, aiding in propulsion through the water.
# '''Teeth''': They have long, sharp teeth that are conical in shape. These teeth are well-adapted for catching and grasping prey, primarily fish and crustaceans.
# '''Eyes''': Their eyes are small in comparison to their body size and are adapted for seeing in the often murky waters of the Amazon basin. Their vision is likely not their primary sense, as they rely more on echolocation.
# '''Sexual Dimorphism''': Adult males are generally larger and bulkier than females, with more pronounced melons on their foreheads.
# '''Skin''': Their skin is relatively smooth and often appears shiny. It lacks the typical dorsal ridge found in other dolphin species.
