An empirical equation is obtained for the dependence between the body weight and the oxygen consumption rate of Menippe mercenaria. The dependence of the crab body liquid osmotic concentration on the salt concentration in environment is ascertained. This dependence shows that crabs display hyperosmotic regulation under conditions of salinity of less than 28‰. When salinity is normal or raised the body fluid of crabs is isoosmotic lowered to the surrounding medium. When crabs are put directly in water with a lowered salinity as well as after long acclimation to these conditions, there are no changes in intensity of the oxygen consumption by crabs. M. mercenaria has highly developed anaerobiosis capacity: under the conditions when oxygen is altogether lacking it can live in the course of 21 hours and then under oxygen conditions quickly recovers its functions. The dependence of the respiration rate on the degree of animal oxygen provision is deduced. A conclusion is drawn as to the eurybiontic character of M. mercenaria; in this connection the Menippe mercenaria can be a good object for artificial breeding and acclimatization in new regions.
