Osmotic and ionic regulation,ntrations far above those of the environment (hyperosmotic regulation), whereas in their marine phase they maintain internal concentrations little more than a third of those of the sea water (hyposmotic regulation).

Designentscheidungen: Das DO-ID-Modellifferent routes, both vertebrate groups have attained the same association of nervous and glandular tissue that has made possible the integration of endocrine functions and the adaptation of hormonally controlled physiological processes to changes in the external environment.
