Smallest cetacean on Earth; restricted to a tiny range of less than 2,000 km²; produces high-frequency clicks for echolocation
🌿 Ecology
HABITAT
Shallow, murky, warm waters of the northern Gulf of California where warm and cold currents mix to produce rich upwellings
DIET
Carnivore
GEOGRAPHIC RANGE
Endemic to the northern Gulf of California, Mexico — the most restricted range of any marine mammal
REPRODUCTION
Single calf born every 2 years; slow reproductive rate makes population recovery almost impossible at current mortality levels
DIET DETAILS
Small fish, squid, and crustaceans caught in the turbid shallow waters of the upper Gulf
⚠️ Threats & Conservation
PRIMARY THREATS
Entanglement in illegal gillnets set for totoaba fish (whose swim bladders are smuggled to China); insufficient enforcement of the gillnet ban
💡 Interesting Facts
1
The Vaquita is the world's most endangered marine mammal — fewer than 10 individuals are believed to survive as of 2024, making extinction in the wild virtually certain without emergency intervention.
2
The Vaquita was not scientifically described until 1958; by the 1990s gillnet bycatch had already reduced the population to the hundreds; the species has been in freefall ever since.
