[Ecological characteristics of Arenicola marina L. (Annelida, Polychaeta) and its morphological and biochemical adaptation to burrowing].
Hydrochemical conditions developing in the burrows of lugworms (Arenicola marina L.) by the end of low-tide period are analyzed. The behavior of lugworms in the course of gradual decrease in the content of dissolved oxygen is described. Quantitative data on the hemoglobin contents in the blood of lugworms from different regions of the White Sea are presented. Morphological and biochemical adaptations facilitating the survival of these animals in their narrow burrows upon sharp fluctuations of environmental conditions, which are characteristic of the littoral zone, are discussed.
