A little known small cetacean, existing only in the Sea of Cortez, is in danger of extinction. Changes to fisheries and local involvement are needed to save the vaquita.

The Difference Between Dolphins and Porpoises
People often use "dolphin" and "porpoise" as if they are interchangeable terms, but there are key differences that make these aquatic mammals different from one another.

Study: Whale Deaths on the Rise
In what appears to be the first global estimate of the problem of whale entanglements, scientists estimate nearly 1,000 whales, dolphins and porpoises drown every day after becoming tangled in fishing nets and other equipment.

Whales, Dolphins and Ocean Noise
Whales and dolphins rely heavily on echolocation and vocalization to find food and communicate. Boat traffic, sonar, oil and gas exploration and navy exercises interfere.

Scientists, NOAA kick off tagging program
On a crowded beach in Florida last month, scientists from the National Oceanic and Atmospheric Administration kicked off a research tagging program that allows biologists to study the highly endangered North Atlantic right whale. Data from the tagging project will be used to help scientists determine when calving right whales are most vulnerable to ship strikes and whether the whales detect and react to passing vessels.
