The fin whale, a type of baleen whale, can hear sound waves that are either shorter or longer than its body, thanks to its specialized skull. Weaning probably occurs on, or en route to, summer feeding areas. The speed and distance sound travels are … These results demonstrate that anthropogenic noise, even at frequencies well above the blue whales' sound production range, has a strong probability of eliciting changes in vocal behavior. In Washington State inland waters, it is illegal to approach a killer whale within 200 yards. Blue whale calls last between ten and thirty seconds.

To understand the health of marine mammal populations, scientists study unusual mortality events. Normally sounds from these whales are too low for humans to hear. Image credit: NOAA Fisheries. Although the cause often remains unknown, scientists can sometimes identify strandings due to disease, harmful algal blooms, vessel strikes, fishing gear entanglements, pollution exposure, and underwater noise. It is hard to track and count their population. Learn more about our marine life viewing guidelines >.

All blue whales are protected under the MMPA. Racing whales. Humans can only hear part of the whales' songs. The range of frequencies that whales use are from 30 Hertz (Hz) to about 8,000 Hz, (8 kHZ). Blue whales can be affected even by sounds that are outside their vocalisation range. Understanding and investigating marine mammal UMEs is important because they can serve as indicators of ocean health, giving insight into larger environmental issues that may also have implications for human health and welfare. Blue whale calves are the biggest babies on Earth, easily, and at birth already rank among the largest full-grown animals. Under the Marine Mammal Protection Act, an unusual mortality event (UME) is defined as "a stranding that is unexpected; involves a significant die-off of any marine mammal population; and demands immediate response." without the dot, and is 30 feet tall.

Whale SENSE is a voluntary education and recognition program in the U.S. Atlantic and Alaska Regions. Antarctic blue whales are generally larger than other blue whale subspecies. This is a far wider range of hearing than human beings enjoy. Environmental modeling to predict where blue whales are in near-real time. Stay at least 100 yards away. An unnamed subspecies of blue whale is found in the southeastern Pacific Ocean, particularly in the Chiloense Ecoregion, and migrates to lower latitude areas, including the Galapagos Islands and the eastern tropical Pacific.
