If oil is the cause of these health problems, how could it make the dolphins so sick? Because of their small population size, vaquitas are experiencing a negative Allee effect, attributing to even smaller population growth rates, driving them further into extinction. [32] Aspects of illegal fishing include open access fisheries and absent fisheries management has correlated towards poaching of the main prey source of the vaquita. Porpoises tend to be smaller seldom exceeding 7 feet in length, whereas many dolphin species can exceed 10 feet in length. False killer whales (Pseudorca crassidens) in the Gulf of Mexico.

The National Institutes of Health also is conducting research into the potential health effects of the oil spill. [4][2], The vaquita was defined as a species by two zoologists, Kenneth S. Norris and William N. McFarland, in 1958 after studying the morphology of skull specimens found on the beach. It has been listed as critically endangered since 1996. It has a very restricted distribution, occurring only in the upper Gulf of California in Mexico, mainly north of 3045N and west of 11420W. Dolphins typically have more say in the environment in which they choose to reside.

With the exception of the Gulf of Mexico, this dolphin stays mainly in the Pacific and Indian oceans. Some experts, like Omar Vidal, Mexicos director of the World Wildlife Fund, oppose the capture plan, which could risk killing the few remaining vaquitas and open up a free-for-all of illegal fishing once they are removed from their natural habitat. dolphins 9 Incredible types of dolphins in mexico Frasers Dolphin.

When detected, the PAH concentrations were at least two orders of magnitude lower than the corresponding FDA level of concern for each PAH. [33] Efforts are proactive in incentive applications to fisheries in a system of trade-offs that benefit fishermen and the vaquita. [41] Breeding in captivity has successfully saved species such as the red wolf and California condor, but the vaquita has only been scientifically described since the 1950s and has never been bred or even held in captivity.
