  RIGHT WHALE
Right whales were named by whalers who considered them the "right" whales to hunt, since they were rich in blubber, they were easy to catch (they are relatively slow swimmers) and they floated after being killed.
Right whales (like all baleen whales) are seasonal feeders and carnivores that filter feed plankton and tiny crustaceans like copepods, krill, pteropods, etc., from the water.
Northern right whales are near extinction due to past hunting pressures and are an endangered species; it is estimated that there are 500-1,000 northern right whales alive and they are near extinction.

 Right whale dolphin - Wikipedia, the free encyclopedia
The right whale dolphins, the Northern Right Whale Dolphin (Lissodelphis borealis) and the Southern Right Whale Dolphin (Lissodelphis peroni), are two of the easiest cetaceans to identify at sea.
The Northern Right Whale Dolphin is widely distributed in the temperate North Pacific in a band running from Kamchatka and mainland Japan in the west to British Columbia down to the Baja California peninsula in the east.
However tens of thousands of the northern species were killed in the 1980s due to them becoming caught in oceanic drift gillnets introduced at that time.

 MBNMS: Cetaceans (whales, dolphins and porpoises)
Though virtually all populations of large whales are greatly reduced, the gray whale population is an exception: the population in 1988 was an estimated 21,100-23,000 individuals (U.S. Marine Mammal Commission 1995), probably close to historical values.
Dolphins and porpoises commonly observed in pelagic waters of the MBNMS include: Pacific white-sided dolphin, northern right whale dolphin, Risso's dolphin, long- and short-beaked common dolphin, killer whale and Dall's porpoise (Table 1 and Table 2).
Pacific white-sided dolphins are commonly seen near the shelfbreak (primarily within 15 km west of Carmel Bay and within 25 km southwest of Santa Cruz) during fall and least abundant during spring (Black 1995).

 ACS - American Cetacean Society
The right whale may have received its name from whalers who thought that it was the "right" whale to kill because it was correct commercially (oil came from whales in those days), or because it was considered "proper" or "true" which meant typical of whales in general.
Right whales are fl all over except for the belly, where there is often a white patch.

 Dolphin World - Information
Other species of dolphins live in cold waters, such as the Atlantic white-sided dolphin that can be seen from the Gulf of St.Lawrence to the North Sea, and the hourglass dolphin that lives in the waters of the Antarctic.
Unlike us, dolphins breathing is not automatic, so they have to think to breathe rather than think to hold their breath.
Therefore, as a dolphin swims, it moves its head back and forth to scan its surroundings, while the echos it sends out bounce off objects and hit the lower jawbone, which conducts the returning sound waves to the inner ear.

Right whales are safer in Canada's Bay of Fundy thanks to WWF and its partners.
As up to two-thirds of the remaining 350 or so right whales once again begin gathering in the Bay of Fundy, a new analysis shows that last July's repositioning of the shipping lanes was indeed a life-saver.
During the summer of 2003, after the lanes were moved, only 1 percent of all right whale sightings occurred within the new lanes, while almost 30 percent of the sightings put right whales in the former path of ship traffic.

The findings refute suggestions by whaling nations such as Japan that a resumption of hunting is justified by the increase of many whale populations beyond their natural size, the researchers said.
The study concludes that as many as 900,000 humpback, minke and fin whales probably navigated the waters of the North Atlantic before their numbers were decimated by commercial whaling in the mid 19th and early 20th century -- several hundred thousand more than previously thought.
LFA testing off the Island of Hawaii in 1998 caused humpback whales to leave the test area, apparently resulted in separation of whale and dolphin calves from their mothers, and injured a snorkeler in the water.
