  1. aStatistical test was an unequal sample sizes and unequal variance t-test. Wavelength and amplitude showed no significant difference but frequency and wave velocity showed significant difference with P⩽0.01.
  2. b‘L’ indicates the distance from the tip of the head to the tail end of individual worm.
  3. cAmplitude is measured at the point of distance s=0.1 L.
