The conservation status of the toothed whales has worsened dramatically since 2001. Since then, more species have been listed in the IUCN Red List as Vulnerable and Nearly Threatended, while the Baiji river dolphin, which used to live in the Yangtze River, is now probably extinct. One major threat to toothed whales world wide is entanglement in fishing gear.
