Speed of sound in Euphausia superba
Journal home page: http://scitation.aip.org/jasa/ The speed of longitudinal sound waves in Antarctic krill has been measured by the time-of-flight method. The result of 17 separate measurement series on different assemblages of living krill is that the animal's sound speed exceeds that of seawa...
