A spate of dolphin attacks on swimmers in Japan’s Fukui Prefecture is being blamed on one bottlenose dolphin, who researchers believe may be particularly lonely, having been separated from a pod ...
To the surprise of those who saw him, Moby Doll was a docile, non-aggressive whale who made no attempts to attack humans. [206] In 2002, the orphan Springer was successfully returned to her family. Between 1964 and 1976, 50 orcas from the Pacific Northwest were captured for display in aquaria, and public interest in the animals grew.
The dolphins drive a school of fish towards the shore where humans await with their nets. In the confusion of casting nets, the dolphins catch a large number of fish as well. Intraspecific cooperative foraging techniques have also been observed, and some propose that these behaviours are transmitted through cultural means.
Pacific white-side dolphin (Sagmatias obliquidens) at Gulf of the Farallones National Marine Sanctuary Gray's Paradox is a paradox posed in 1936 by British zoologist Sir James Gray . The paradox was to figure out how dolphins can obtain such high speeds and accelerations with what appears to be a small muscle mass.
Humpback whale breach sequence. A breach or a lunge is a leap out of the water, also known as cresting. The distinction between the two is fairly arbitrary: cetacean researcher Hal Whitehead defines a breach as any leap in which at least 40% of the animal's body clears the water, and a lunge as a leap with less than 40% clearance.

The common bottlenose dolphin or Atlantic bottlenose dolphin (Tursiops truncatus) is one of three species of bottlenose dolphin in the genus Tursiops.The common bottlenose dolphin is a very familiar dolphin due to the wide exposure it receives in human care in marine parks and dolphinariums, and in movies and television programs.

Researchers found an increase in common dolphin sightings in the English Channel and Hebrides, and a decline in white-beaked dolphins in the Hebrides.
The dolphin teams were trained to detect and mark mines either attached to the seafloor or floating in the water column, because dolphins can use their echolocative abilities to detect mines. The sea lion team retrieved test equipment such as fake mines or bombs dropped from planes usually out of reach of divers who would have to make multiple ...
