At such times they usually discharge their ink in large quantities.
135. oldal - Light as a flake of foam upon the wind, Keel upward from the deep emerged a shell, Shaped like the moon ere half her horn is filled ; Fraught with young life, it righted as it rose, And moved at will along the yielding water. The native pilot of this little bark Put out a tier of oars on either side, Spread to the wafting breeze a twofold sail, And mounted up and glided down the billow In happy freedom, pleased to...
177. oldal - They are often found in the morning stranded on the beaches in immense numbers, especially when there is a full moon, and it is thought by many of the fishermen that this is because, like many other nocturnal animals, they have the habit of turning toward and gazing at a bright light, and since they swim backwards they get ashore on the beaches opposite the position of the moon.

24. oldal - It will be seen from the above that the study of the species of multilocular shells is encompassed with great difficulties, owing to the variability of their characters ; in fact the synonymy of the species of Ammonites has been greatly increased in consequence of several names being given to the same species at different periods of its growth. The living Nautilus also, undergoes a change of form. At a recent meeting of the Boston Society of Natural History, Prof.
176. oldal - In this position it would wait until the fishes came back, and when they were swimming close to or over the ambuscade, the squid, by a sudden dart, would be pretty sure to secure a fish. Ordinarily, when swimming, they were thickly spotted with red and brown, but when darting among the mackerel they appeared translucent and pale. The mackerel, however, seemed to have learned that the shallow water...
185. oldal - The frontal portion is considerably broken, but the dorsal portion appears to extend nearly to the posterior end, the length from the point of the beak to the posterior edge being 34 inches. The texture is firmer and the lamina are relatively thicker than in A. monachus. The rostrum and most of the frontal regions are black and polished, gradually becoming orange-brown and translucent toward the posterior border, and marked with faint striae radiating from the tip of the beak, and by faint ridges...
