[13] [14] The only known predator of the Pacific white-sided dolphin is the killer whale, [15] but at least one case of predation by the great white shark has been recorded. [16] The total population may be as many as 1 million. [6] However, the tendency of Pacific white-sided dolphins to approach boats complicates precise estimates via sampling.
It provides breeding and feeding grounds for at least twenty-five endangered or threatened species; thirty-six marine mammal species, including blue, gray, and humpback whales, harbor seals, elephant seals, Pacific white-sided dolphins, and one of the southernmost U.S. populations of threatened Steller sea lions; over a quarter-million breeding ...
The remaining four species in the genus Lagenorhynchus—the Pacific white-sided dolphin, Peale's dolphin, hourglass dolphin and the dusky dolphin—are consistently placed within the Lissodelphininae subfamily, in studies of molecular phylogeny, [8] [4] together with the right whale dolphin and the four species of the genus Cephalorhynchus ...
The tour agency said its team counted 33 gray whales, 1,500-plus Risso's dolphins and three northern right whale dolphins as they undertook the 60-mile roundtrip from Monterey to Point Sur. Rare ...
A mega-pod of dolphins put on a special show when it appeared next to Evan Donadt's San Diego whale watching boat. While passengers were hoping to spot a blue whale during the height of the whale ...
The “super pod” of Risso’s dolphins was spotted in Carmel Bay, off central California’s coast. This species , which can grow to over 10ft long and weigh as much as half a metric tonne, is ...

Twelve species of dolphins occur in California's waters. Short-beaked common dolphin, Delphinus delphis [1] Long-beaked common dolphin, Delphinus capensis [2] Short-finned pilot whale ...
The origins of the program date back to 1960, when a Pacific white-sided dolphin was acquired for hydrodynamic studies seeking to improve torpedo performance. [1] The aim was to determine whether dolphins had a sophisticated drag-reduction system, but the technology of the day failed to demonstrate that dolphins have any unusual capabilities in this respect.
