The Sun-fish is exceedingly rare. A large specimen was captured off Start Point in 1864. Attention was first drawn to a huge dark object on the water. On a boat being sent out, it was soon discovered to be the back fin of a very large fish, apparently asleep. A very exciting chase commenced, extending over an hour, the crew meanwhile battling with harpoons, boat-hooks, &c.; the fish trying several times to upset the boat by getting his back under it. At length a line was thrown over its head, and the fish, being weakened by the struggle, was towed alongside the yacht, hoisted on board, and slaughtered. Yarrell, in his work on British Fishes, states the largest Sun-fish to be about 3 cwt., but the above specimen weighed nearly 6 cwt. Sun-fish are found occasionally in the tropical seas of large dimensions, but those found in the Channel seldom if ever exceed from 1 cwt. to 2 cwt. The peculiarities in regard to this fish are, that it has no bones, but the whole of the formation is of cartilage, which can easily be cut with a knife. The skin is cartilage of about an inch and a-half thick, under which there is no backbone or ribs. This specimen was of extraordinary dimensions--5 ft. 10 in. in length, and 7 ft. from the tip of the dorsal to the point of the anal fin. The "Courrier de Sagon" brings, as a contribution to Natural History, the not very credible-sounding description of a fish called "Ca-oug" in the Anamite tongue, which is said to have saved the lives already of several Anamites; for which reason the King of Anam has invested it with the name of "Nam hai dui bnong gnan" (Great General of the South Sea). This fish is said to swim round ships near the coast, and, when it sees a man in the water, to seize him with his mouth, and to carry him ashore. A skeleton of this singular inhabitant of the deep is to be seen at Wung-tau, near Cape St. James. It is reported to be thirty-five feet in length, to have tusks "almost like an elephant," very large eyes, a black and smooth skin, a tail like a lobster, and two "wings" on its back.[15] The Grouper must be a voracious fish, for we read of a specimen being caught off the coast of Queensland, which is thus described:--"It was 7 ft. long, 6 ft. in circumference at its thickest part, and its head weighed 80 lb. When opened, there were found in its stomach two broken bottles, a quart pot, a preserved milk tin, seven medium-sized crabs; a piece of earthenware, triangular in shape, and three inches in length, incrusted with oyster shells, a sheep's head, some mutton and beef bones, and some loose oyster shells. The spine of a skate was imbedded in the Grouper's liver."
