Life After Rescue
Helen, the Pacific white-sided dolphin (Lagenorhynchus obliquidens) at the Vancouver Aquarium was rescued after becoming entangled in a fixed-fishing net. She was transported here after being confirmed unreleasable by government because of her injuries. She's now helping researchers understand how dolphins navigate underwater using sound (echolocation) and why they get caught in fishing nets. This is an important issue, as in the wild each year over 300,000 cetaceans (whales, dolphins and porpoises) die as unintended bycatch after becoming entangled in fishing gear.
