Humpback whales also occur in much of the range of the North Pacific right whale, including in the Bering Sea, and parts of the highly variable and complex humpback calls can be similar to right whale calls, similar enough that confirmation that a call is in fact from a right whale usually requires a human to review the entire context of the ...
The right whale's callosities provide habitat for large colonies of cyamids or whale lice, which feed on the right whale's skin as these small crustaceans cannot survive in open water. [13] The relationship between cyamids and right whales is symbiotic in nature but is poorly understood by scientists.
Fewer than 400 individual North Atlantic right whales remain in the wild, and their numbers continue to decline. Oceana, a conservation group based in D.C., has reported numerous collisions ...
Each year, a number of North Atlantic right whales get formal names. Scientists just released this year's list. What goes into naming a whale?
According to NOAA, about 360 North Atlantic right whales still exist, with fewer than 70 reproductively active females. NOAA lists two other species of right whale: North Pacific (found in the ...
