US Navy Dispatches Military Dolphins In Effort To Save “Smirking” Porpoise From Extinction

Read Time:1 Minute, 33 Second

The world’s smallest porpoise, the vaquita, or “little cow,” is also smaller in number as its population has been decimated in recent decades thanks to what the Washington Post describes as “a cruel mixture of fishing nets and economics.”

The unlikely mammal has gotten tangled up in fishnets since World War II, when fishermen began to seriously hunt a species of sea bass called totoaba. The unusual porpoise, known for sporting a little smirk, is a marine mammal that would drown in the nets when they couldn’t swim to the surface for air. The appetite for totoaba has not diminished because the fish’s bladder is used in Chinese medicine and considered a delicacy there, fetching more than $4,000 for just one. The Mexican government has frantically decided to try to capture the remaining survivors, now around 60, to try to save the species.

The US Navy is joining in as well, volunteering another marine mammal to help: the dolphin. The Navy is training the so-called Seal Team 6 of dolphins, which already prowl around for underwater mines, to find the last surviving vaquita, which live between the Mexican mainland and Baja California Peninsula. “Their specific task is to locate,” one expert says. “They would signal that by surfacing and returning to the boat from which they were launched.”

Sadly, the vaquita doesn’t thrive in captivity, where they would need to remain to be safe from fishing nets. They also reproduce very slowly, with one calf every other year.

Not everyone is buying into the plan, adds Live Science. “I don’t like this idea at all,” says a rep for World Wildlife Fund Mexico. “The risk of killing a vaquita while catching them is very high. With only 50 or 60 animals left, we can’t play with that.”
