River dolphins are among the most endangered mammals on Earth, with populations declining from bycatch, boat strikes, pollution, and habitat degradation in the major river systems they inhabit.
River dolphins entangled in fishing nets drown after struggling against restraint — a welfare harm compounded by the conservation crisis each individual represents. Mercury poisoning from mining contamination causes neurological damage and reproductive impairment in Amazon river dolphins. River dolphins navigating increasingly degraded and noisy waterways experience chronic sensory disruption to their echolocation systems. Protecting river dolphins requires tackling multiple simultaneous threats including fishing gear, pollution, boat traffic, and habitat degradation across the large river basins they inhabit.
