Some dolphin species are in danger of becoming extinct, and alarming statistics suggest that illegal dynamite fishing, entanglement in fishing nets, collisions with boats and propellers, marine pollution, disease and beaching due to sonar interference, kill an increasing number of dolphins every year.

This would make the baiji the first cetacean—that is, dolphin, porpoise or whale—to go extinct because of humans. The species was probably driven to extinction by harmful fishing practices ...

In 2006, a freshwater species of dolphin was declared functionally extinct. Its extinction was mainly attributed to the destruction of its habitat. The last known encounter of these dolphins was in 2002.

In recent history the Baiji, also known as the Yangtze river dolphin, was declared critically endangered, its river habitat ruined by the construction of dams and the invasion of boat traffic. Similarly, endangered dolphins like the Maui’s dolphin are on the brink of extinction due to entanglement in fishing gear.

The protection of the Irrawaddy dolphin is crucial for the overall health of the Mekong River—home to an estimated 1,100 species of fish. The Irrawaddy dolphin is also regarded as a sacred animal by both Khmer and Lao people, and is an important source of income and jobs for communities involved in dolphin-watching ecotourism.

Living close to shore is a problem for the dolphins. Bycatch—becoming tangled in recreational and commercial gill and trawl nets—is the biggest threat they face. Gillnets, for example, are made of a fine mesh that dolphins are unable to detect underwater and they accidentally swim into them and become caught.

The baiji holds the unfortunate award for being the first whale or dolphin to be driven to extinction by humans; the baiji was sacrificed to population pressures and industrialisation of China. Entanglement in fishing equipment and habitat destruction resulted in the serious decline of the baiji from the mid-1900s and the building of the Three Gorges Dam lead to further loss of habitat.

The new list documents an additional 31 species as extinct in the wild including species of fishes, sharks, and frogs. There are now 1,28,918 species on the IUCN Global Species Programme and nearly a third or 35,765 of them are threatened with extinction. These include all of the world’s freshwater dolphins, about one-third of all oak trees ...

Some do's and don'ts of watching dolphins in the wild include: Do not feed wild dolphins. It teaches them to be dependent on humans, can lure them into dangerous areas along the shore, and encourages bad habits. If you see someone feeding dolphins in the wild, report them to the authorities.
