The peculiarities of the oxygen dissociation curve are hard to understand if we assume that the worm is trying to do with its haemoglobin the same kind of things that we do with ours, and one may seriously doubt whether the pigment ever plays a part in oxygen transport. The physiological adaptation of the lugworm, Arenicola marina, to cope with the sulphide levels in its environment was studied. 33, Moscow, 119071, RussiaYou can also search for this author in Download citation.

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. The internal concentrations of sulphide, however, never reach the external values when pH is above 7. DOI: https://doi.org/10.1007/BF02367136 The tail is a means of communicating with the sand surface in comparative safety, and the parapodia at the two ends of the trunk are divergently specialised in accordance with different types of movement. Arenicola marina: a model of physiological adaptation 39 the functional differentiation of the gut and, in addition, have qualitatively analysed the hydrolysis of various compounds assumed to be components of the natural food (Ker- mack, 1955; Longbottom, 1970; Hylleberg-Kristensen, 1972). is seen in its most typical form when the burrow is covered over by water. The peculiarities of the oxygen dissociation curve are hard to understand if we assume that the worm is trying to do with its haemoglobin the same kind of things that we do with ours, and one may seriously doubt whether the pigment ever plays a part in oxygen transport.

Hydrochemical conditions developing in the burrows of lugworms (Arenicola marina L.) by the end of low-tide period are analyzed. The worm's body is divided into regions by local modifications of the metameric segmental plan. The worm generally lives in a burrow of characteristic form, and for most of the time it carries out a regular rhythmic sequence of movements (the Normal Cyclical Pattern), determined by certain spontaneous pacemakers and serving to integrate its various necessary activities. The properties of Arenicola haemoglobin are considered as an example of physiological adaptation. and Reish, D.J., The Effects of Varying Dissolved Oxygen Concentrations on the Hemoglobin Levels of the Polychaetus Annelid Sveshnikov, V.A., Biocenotic Connections and Living Conditions of Some Food Invertebrates of the Littoral Infauna of Kandalaksha Bay, White Sea, Toulmond, A., Tide-Related Changes of Blood Respiratory Variables in the Lugworm Wells, G.P., Respiratory Movements in Polychaetes, Especially Russian Academy of Sciences, Severtsov Institute of Ecology and Evolution, Leninskii pr.

In special circumstances, the worm carries out alternative behaviour sequences, apparently unrelated to the N.C.P. The functional significance of some of these regional differentiations is clear.
