The vaquita is the smallest cetacean, reaching a maximum length of 1.5 meters and is endemic to Mexico where it only lives in the upper Gulf of California. It also faces the highest risk of extinction of all cetaceans in the world; it is estimated that there are less than 20 individuals alive today. In an effort to save this animal, the government of Mexico recently approved new regulations that promote sustainable fishing practices. Drift gillnets, the biggest threat to vaquitas, will be gradually substituted with selective fishing gear that won’t harm the endangered animal while allowing fishermen to continue to earn a living.
