Abstract: | It was established that the process of repeated attachment to a substrate in bivalve mollusks Crenomytilus grayanus (Gray s mussel) and Modiolus modiolus (the northern horse mussel) involved several successive stages which took in vitro about one month at a water temperature of 19 ± 2°C. Comparison with Gray s mussel revealed that the northern horse mussel had a higher rate of byssal thread production and a greater thread number by the end of the complete formation of the byssus complex. The observed differences are explained by the adaptation of mollusks to habitation in different biotopes.Original Russian Text Copyright © 2004 by Biologiya Morya, Selin, Vekhova. |
