Habitat
Orinoco river dolphins primarily inhabit the freshwater rivers and tributaries of the Orinoco River basin in Venezuela and Colombia. They prefer deep, slow-moving waters, including main channels, flooded forests, and lakes, avoiding fast currents and shallow areas.
Diet
Orinoco river dolphins mainly eat fish such as catfish, piranhas, and characins, along with crustaceans and occasional small turtles. They use echolocation to hunt in murky waters, typically feeding during the day in schools of fish.
Behavior
Orinoco river dolphins are usually solitary or in small groups of up to five individuals, showing curious and playful behavior towards boats. They are diurnal, active during the day for hunting and socializing, and use echolocation for navigation in turbid rivers. They exhibit territorial displays during mating season and are known for their agility in maneuvering through obstacles.
Conservation Status
The IUCN status for Inia geoffrensis is Vulnerable, with the Orinoco subspecies facing a declining population due to threats like habitat destruction from dams, pollution, and bycatch in fishing nets.
