Mexico has captured a rare vaquita marina porpoise - a female of reproductive age - as part of a last-ditch bid to save the critically endangered species.
The vaquita, the world's smallest porpoise, has been pushed to the brink of extinction by illegal gillnet fishing and there are just 30 left in the wild.
Mexican and conservation groups have launched a plan to save the species by transporting as many as possible to a protected marine reserve.
"The @VaquitaCPR team has managed to capture another vaquita marina," Environment Minister Rafael Pacchiano said, adding vets are in charge.
The first captured - a six-month-old calf - was caught last month but had to be released as it was too young to be separated from its mother.
The vaquita has been nearly wiped out by gillnets used to fish for another species, the also endangered totoaba fish, whose swim bladder is considered a delicacy in China and can fetch US$20,000 (HK$156,000) a kilo.
