Hunt for Endangered Porpoises in Mexico.
Mexican officials and Sea Shepherd are launching a search expedition to locate the few remaining vaquita marina, the world’s most endangered marine mammal, in the Gulf of California. The elusive porpoises are threatened by illegal gillnet fishing, which also impedes population calculations. The expedition will use binoculars, sighting devices, and acoustic monitors to try to pinpoint the location of the vaquitas. The last sighting expedition in 2021 yielded probable sightings of between 5 and 13 vaquitas, a decline from the previous survey in 2019.
