MEXICO CITY, May 11 (Reuters) - Mexico's President Enrique Pena Nieto wrote to Leonardo DiCaprio on Twitter on Thursday in a bid to reassure the Hollywood actor his government was taking steps to protect a rare porpoise in Mexican waters teetering on the brink of extinction.
Populations of the vaquita, a tiny snub-nosed porpoise that lives in the Gulf of California, have dropped sharply in recent years due to gillnet fishing for shrimp and totoaba, a popular delicacy in Asia, sparking increased international concern.
On Wednesday, DiCaprio urged his 17.5 million Twitter followers to get behind a World Wildlife Fund effort to raise awareness and help save the vaquita before it was too late.
On Thursday evening, Pena Nieto took to Twitter in English to defend his government's efforts on behalf of the diminutive sea mammal, addressing the actor directly with his first tweet.
"I welcome @LeoDiCaprio and @World_Wildlife's concern regarding the Vaquita Marina," Pena Nieto wrote. "@Mexico has focused all its efforts to prevent the extinction of this species," he said before sending out five more tweets, all in English, to draw attention to what Mexico is doing.
Mexico imposed a two-year ban on gillnet fishing in the vaquita's habitat in 2015, extending it earlier this year. Still, critics have complained the ban needs better enforcement.
Viva Vaquita, a group dedicated to saving the porpoise, says on its website that the vaquita population was estimated to be below 50 in January 2017, based on earlier study findings. (Reporting by Dave Graham; Editing by Paul Tait)
