Bolivia rescues 24 dolphins trapped in shallow river

STORY: The dolphins, of which 14 were females and 10 were males, were relocated to the Rio Grande river.

According to research associate and volunteer at the Noel Kempff Natural History Museum, Claudia Venegas, peaceful spots such as the one in which the specimens were found are used by pregnant females to give birth, but changes in the hydrological basin caused the dolphins to be unable to follow the natural course of the main riverbed, leaving them trapped as water levels dropped.
