Phocoena sinus, a small and critically endangered cetacean found in the Gulf of California. The vaquita (Fig. 1) is one of the smallest cetaceans in the world, with mature individuals measuring approximately 1.5 m (4.9 ft) in length and weighing about 50 kg (110 lb). Females are slightly larger than males. Vaquitas live for approximately 20 years and breed for the first time at between 3 and 6 years of age. Breeding is seasonal, and females produce a calf every other year, usually in March or April. The range of the vaquita is limited to the northern Gulf of California, mainly an area of only around 4000 km2 (1544 mi2). See also: Cetacea; Marine ecology
