After nine or ten months, it is difficult to tell mother from child. They're semi-aquatic mammals, which means that they need both land and water habitat to survive. Early travelers' reports describe noisy groups surrounding explorers' boats, but little scientific information was available on the species until Duplaix's groundbreaking work in the late 1970s. Giant otters are a species of South American mammals belonging to the Pteronura genus. Carter and Rosas, however, rejected the subspecific division in 1997, noting the classification had only been validated once, in 1968, and the P. b. paraguensis type specimen was very similar to P. b.
