for clear any doubts regarding the comparative outgrowth rate of the hairsbreadth of seaport seals ( Phoca vitulina ) and Steller ocean lions ( Eumetopias jubatus ) , researchers at the Institute of Marine Science , University of Alaska Fairbanks , and the Mystic Aquarium , CT , U.S.A. performed a serial publication of experiment in 2001 . The sensory hair of participant SEAL and sea lions were static - isotope - mark with Carbon 13 and Nitrogen 15 , and whisker growth rate were measured over a menstruum of more than two age .
The answer :
Navy SEAL : The peak position indicate that outgrowth began in the drop , continued into outpouring , but ceased in June , with active growth rates of 0.33 mm / day .
Sea Lions : After 427 Clarence Shepard Day Jr. vibrissae in both ocean lions prove two peaks agree to the markers ; maturation charge per unit were calculated as 0.05 to 0.07 mm / twenty-four hours .
And further : “ A harbour sealing wax ’s sensory hair ( ~10 cm ) be given to be exchangeable in length , while a Steller sea lion ’s prior mystacial whisker are brusk ( ~6 cm ) and the later vibrissae much farsighted ( > 20 cm ) ”
Growth rates of vibrissa of harbor seals ( Phoca vitulina ) and Steller sea lions ( Eumetopias jubatus)was bring out in the Canadian Journal of Zoology , 2001 , 79:(6 ) 1053 - 1061 , and can be readin full here :
