Information about the Amazon River Dolphin:
The Amazon River Dolphin is is a freshwater mammal native to the rivers and flooded rainforests of Brazil, Bolivia, Peru, Ecuador, Colombia and Venezuela. Amazon River Dolphins grow to be about 8.5 to 9.5 feet long (2.5 to 3 meters) and weigh about 200 pounds. Males are normally larger than females. Unlike other dolphins, the Inia geoffrensis does not have a dorsal fin, but rather a uneven shaped hump on its back. During the dry season, these dolphins live in the larger rivers in the rainforest, but during the rainy season the dolphins head into the flooded plains swimming among the submerged trees hunting for prey. These freshwater mammals have about 100 peg-like teeth for catching food. The river dolphin’s diet consists of small crustaceans like crabs, small turtles, catfish, piranhas, and other fish.
