Sea Shepherd’s Operation Milargo (Miracle) in the Sea of Cortez
Sea Shepherd Conservation Society is a non-profit marine conservation organization whose mission is to end the slaughter of wildlife and destruction of habitats in the world’s oceans. Sea Shepherd is dedicated to defending all species of ocean wildlife, from the tiniest plankton to the great whales.

Sea Shepherd uses innovative, non-violent, direct-action tactics to investigate, document, and take action when necessary in order to expose and confront illegal activities on the high seas.

By safeguarding the biodiversity of our delicately balanced ocean eco-systems, Sea Shepherd works to ensure their survival for future generations. As Sea Shepherd Founder, Captain Paul Watson says, “If the oceans die, we die!”.

Sea Shepherd Conservation Society’s „Operation Milagro” („Operation Miracle”) is dedicated to the conservation of the endangered vaquita porpoise, a species on the brink of extinction. Sea Shepherd’s new research vessel, the RV Martin Sheen is collecting data in an effort to collaborate with scientific and conservation efforts to contribute to the survival of the remaining vaquitas.

By documenting the plight of these endangered cetaceans and conducting outreach in the region with marine biologists, vaquita experts and other organizations we can achieve this goal. Numerous non-profits and scientists are working in cooperation with the Mexican government and President Enrique Peña Nieto to conserve the remaining vaquita porpoises in their refuge. Mexico is inspiring hope for the vaquitas by taking vital steps to conserve this species found only in the waters of Mexico’s Gulf of California. However, it will take nothing short of a collaborative, concerted effort to protect these shy and peaceful marine mammals from a dire fate. Working together, we can bring about a miracle!
