Abstract
The attachment to substrata of the tubes of Pomatoceros lamarckii and the haptera of Laminaria digitata was examined using light microscopy and scanning electron microscopy. Tenacity was measured for the tubes of P. lamarckii and the haptera of L. digitata. Mean tenacities of 24. 75 x 10(5) N . m(-2) and > 4.22 x 10(5) N . m(-2) respectively were re corded. Evidence of the capability of both organisms to conform exactl y to the contour of the substratum, coupled with the measured tenaciti es, lead to the conclusion that both adhere to substrata by mechanical means.
