Thus we find a peculiar setof animals in the salt marshes which occur here and therealong the coasts; in continental salt lakes which haveno connexion with any present sea ; in hot springs whereanimals may sometimes be foimd flourishing at a tem-perature of 45°C. II. The Pelagic Fauna The conditions of Ufe for open-sea or pelagic animalsmust be regarded as on the whole veryfavourable. Forthere is plenty of room and there are no boundaries tobe dashed against till a shore is reached. A storm canbe avoided by sinking for several fathoms.
