Vaquita

It is found in the region of Gulf of California. It is one of the rarest species of cetaceans in the world itself.The remaining number of Vaquita is just about 200 to 300. It is endangered due to both its limited range and the ease with which it gets caught in the fishing nets.The vaquita is one of the world's most rare marine mammals. It was first described in 1958. Due to its elusive nature, little is known about it. Vaquita are similar to harbor porpoises with respect to life span, patterns of growth, age at sexual maturity, seasonal reproduction, and mating season. In contrast to the harbor porpoise, the calving interval for adult female vaquita may be greater than one year. This has important implications for the potential growth rate of the population and therefore its ability to compensate for human-related sources of mortality and recover from low population levels.
