It has heen netted in Vine- yard Sound as late in the season as December, and occurs as far south as the Gulf of Mexico. On the other hand it is known to wander as far north as Maine. Habits and food.—This shark is a more slender fish than the common mack- erel shark—large, powerful, and swift-swimming, feeding upon small fish and squid. Little is known of its habits, though what has been written of its relative, /. punctatus, probably applies equally to /. tigris. Its breeding habits are not Fia. 14.—White shark ( Carcharodon carcharias) 13. White shark (Carcharodon carcharias Linnteus) Man-eater shark Jordan and Evermann, 1896-1900, p. 50. Garman, 1913, p. 32. Description.—The white shark is of the general "mackerel shark" appear- ance, with firm lunate tail, the upper lobe only slightly longer than the lower, triangular first dorsal of moderate size originating over the armpits of the pecto- rals, which are sickle shaped, and roughly twice as long as broad. The second dorsal and anal fins are very small, and the root of the tail bears a well-marked keel on either side. The snout is pointed. Unfortunately there is no obvious "field mark" to distinguish a small white shark from the common mackerel shark when seen swimming, for while the former is the slimmer fish the difference in form is not great. Once captured, however, no confusion could arise, for instead of the slim catlike teeth of the porbeagle we find the man-eater best armed of all modern sharks, its teeth large and triangular and similar in shape in the two jaws though broadest in the upper, with nearly straight cutting edges and s
