Hello, my name is Vance, and I am a Vaquita. I am also known as the Gulf of California Harbor Porpoise. I live off of Mexico in the Gulf of California (Sea of Cortez). There are only 30 of us left (as of 2018), making us the most critically endangered small cetacean (whale) in the world. Eek, that’s a lot of pressure on us, just trying to stay alive. I’d hate to go extinct just because we live in a limited range.
We are the smallest cetacean, reaching lengths of 4-5 feet (1.2-1.5 meters) and weights of 65-120 pounds (30-55 kg). We are hard for humans to study because we avoid boats if possible. It’s nothing personal, except that we’ve had so much trouble with humans setting out fishing nets (see below). We hang out in pairs, but sometimes we get together in groups of 7-10. We eat schooling fish such as croakers and grunts, as well as crustaceans, squid and octopus
Our greatest threats are through commercial fishing. Gillnets are miles long, and are used to catch shrimp for export to places such as the United States. Shrimp is the most popular seafood of choice there. Gillnets catch anything and anybody in its path, including us Vaquita.
There is also a fish called the Totoaba, whose swim bladders are exported to China for a medicinal soup. This is an illegal fishery, and Vaquita get caught in these nets too.
The bad news is that cetaceans worldwide are caught as bycatch in fishermen’s nets. 300,000 cetaceans die a year, or one every two minutes, just to satisfy human’s demand for seafood.
The good news is that there is a moratorium on gillnets in the Gulf of California for two years. If it gets enforced regularly, then my population of Vaquita have a chance to recover. Females have calves every other year, and the calves already born will have a chance to grow up.
For now, it’s time for my morning meal. It’s time to celebrate!
