Although vaquita have never been hunted directly, populations are declining as a result of incidental mortality in fishing gear called ‘gillnets’. The sound that comes back gives the vaquita information that helps them decide if it’s dinner or not. Vaquitas only live in one small area in the north of the Gulf of California (Sea of Cortez), off Mexico. So although the vaquita is found only in this small pocket of unique marine habitat in north-western Mexico, it is the demand for the swim bladder of the totoaba in China that is driving its extinction. Most phocoenids are restricted to water cooler than 20 degrees Celsius, vaquitas are unique in their ability to tolerate large annual fluctuations in temperature (Hohn, et al, 1996). Averaging 150 cm (for females) or 140 cm (for males) in length, it is the smallest of all living cetaceans. Its skin is dark grey on its back, gradually fading to lighter grey or white on its belly. They are not found anywhere else on Earth. Vaquitas live about a four-and-a … Most phocoenids are restricted to water cooler than 20 degrees Celsius, vaquitas are unique in their ability to tolerate large annual fluctuations in temperature (Hohn, et al, 1996). The sound that comes back gives the vaquita information that helps them decide if it’s dinner or not. Averaging 150 cm (for females) or 140 cm (for males) in length, it is the smallest of all living cetaceans.Today, the species is on the brink of extinction. The Vaquita is a small harbor porpoise native to a very small area in the extreme northern part of the Gulf of California, Mexico.
Its proportionally larger dorsal fin and flippers help a vaquita offload extra body heat in warmer waters. The vaquita can be confused with the harbor porpoise (Phocoena phocoena). The vaquita has also suffered from the demand in China for the swim bladder of the totoaba, an endangered fish that lives in vaquita habitat. An interesting feature of the vaquita is that it is the only species of porpoise that is found in such warm waters. The vaquita porpoise lives in a tiny area in the very northern part of the Gulf of California (Sea of Cortez), between Baja California and mainland Mexico. An interesting feature of the vaquita is that it is the only species of porpoise that is found in such warm waters.
‘Vaquita’ is a Spanish word meaning "little cow". The Maui dolphin, Hector dolphin, Ganges River dolphin, Vaquita, and Baiji dolphins are endangered. The plight of cetaceans—whales, dolphins, and porpoises—as a whole is exemplified by the rapid decline of the vaquita in Mexico, with about 10 individuals remaining. Vaquitas are a quite recently discovered species: they were first identified in 1958 based on skulls and were first observed in 1985. Today, the species is on the brink of extinction. Averaging 150 cm (for females) or 140 cm (for males) in length, it is the smallest of all living cetaceans.Today, the species is on the brink of extinction. They live in the northern end of the Gulf of California, off the Baja Peninsula in Mexico, in murky, shallow waters within about 13.5 miles of shore. Vaquitas only live in one small area in the north of the Gulf of California (Sea of Cortez), off Mexico. Young vaquita calves are nursed for several months before being weaned. Duke University's OBIS-SEAMAP provides a vaquita sightings map. The vaquita (Phocoena sinus), literally "little cow", is a species of porpoise endemic to the northern end of the Gulf of California (Sea of Cortez, Vermilion Sea). Females give birth to one calf about every two years. Although vaquita have never been hunted directly, populations are declining as a result of incidental mortality in fishing gear called ‘gillnets’. The vaquita’s entire range is about 4,000 km2—nearly the size of the state of Rhode Island. There are only 55 Maui dolphins alive today.
They live off the coast of New Zealand. They are recognizable by the dark rings around its eyes and mouth and they have a dark stripe that extends from the chin to the flipper.
The tiny vaquita porpoise (Phocoena sinus) is found only in the shallow waters of the northern Gulf of California, Mexico.It is the most endangered of the 128 marine mammals alive in the world today. Vaquita is the smallest porpoise that belongs to the order Cetacea.
