Archive image from page 623 of The depths of the ocean. The depths of the ocean : a general account of the modern science of oceanography based largely on the scientific researches of the Norwegian steamer Michael Sars in the North Atlantic depthsofoceangen00murr Year: 1912 588 DEPTHS OF THE OCEAN barely be seen in the sea with the naked eye. The two last-mentioned forms are found in warm currents on the coast of Norway, and their presence is feared by the fishermen, because they very often spoil the herring which feed on them ; the shells are very slowly digested and the stomach-contents putrify when the her- __ rings are salted, and then the whole herring (. decomposes. Among the many warm- water species Liniacina biilimoides is characteristic. The Cavolinidse include numerous forms with cornet-shaped shells. Clio pyramidata (Fig. 430) and Diacria trispinosa are very important forms, occurring in vast numbers, and their shells are very numerous in the deposits. Creseis Fig. 429. Lhnacina retroversa, Fleming. (From Sars.) Fig. 430. Clio pyra m id a ta, L (From Boas.) acicula (Fig. 431) and Cavolinia gibbosa (Fig. 432) are characteristic forms. The ' whale's food,' Clione liniacina (Fig. 433), is specially abundant in north- ern waters, and is better known than most of the Gymnosomata. It is 3 or 4 cm. long, perfectly transparent, with red shad- ings and black stomach. In the Polar Sea it may be seen swimming among the ice-floes, but it occurs also in the Nor- wegian Sea, in the Norwegian fjords, and in the Atlantic south of Iceland. The majority of the pteropoda (both species and individuals) are restricted to warm water : in the Atlantic the northern limit for the warm- water forms may be roughly drawn from the Bay of Biscay to New York, and the southern limit from Brazil to the Cape. This area is the real home of Clio pyramidata, C. aispidata, Creseis aciada, the Cavolinidae, the Cymbulidae, Pneumoderma violaceum, Liniacina infiata, L. lesueuri, L. biilimoid
