A blue whale call recorded off Madagascar, a two-unit phrase, [99] consists of 5–7 pulses with a center frequency of 35.1 ± 0.7 Hz lasting 4.4 ± 0.5 seconds proceeding a 35 ± 0 Hz tone that is 10.9 ± 1.1 seconds long. [98] In the Southern Ocean, blue whales produce 18-second vocals which start with a 9-second-long, 27 Hz tone, and then a ...
The gray whale (Eschrichtius robustus), [1] also known as the grey whale, [5] is a baleen whale that migrates between feeding and breeding grounds yearly. It reaches a length of 14.9 meters (49 ft), a weight of up to 41 tonnes (90,000 lb) and lives between 55 and 70 years, although one female was estimated to be 75–80 years of age.
The Bowhead whale can live to be 200 years old or more, and now scientists are hoping clues to longevity could be found in the whale's DNA. As the longest-lived mammal, scientists hoped sequencing ...

[110] [111] They reach sexual maturity when 13 to 14 m (43 to 46 ft) long. Baleen whales are K-strategists, meaning they raise one calf at a time, have a long life-expectancy, and a low infant mortality rate. [112] Some 19th century harpoons found in harvested bowheads indicate this species can live more than 100 years. [113]
