最佳解答:

The following information is about sea horse: Description— The sea horse grotesquely resembles the "knight" in an ordinary set of wooden chessmen in its sidewise flattened body, in its deep convex belly, in its curved neck and in its curious horselike head carried at right angles to the general axis of the body. The head is surmounted by a pentagonal star-shaped "coronet," and the snout is tubular with the small oblique mouth at its tip, like that of its relative the pipefish. It has a sharp spine on each side above the eye and one behind it, a third over the gill cover, and a fourth on the side of the throat, which sometimes terminate in short fleshy filaments; also a blunt horn between the nostrils. Its neck, body, and tail are covered with rings of bony plates, 12 rings on the trunk, 32 to 35 on the tail, and each body ring is armed with four blunt spines. The body tapers suddenly behind the anal fin to a long tail, which is four-cornered in cross section, curled inward, and strongly prehensile. In the male the lower surface of the fore part of the tail bears the brood pouch, opening by a slit in front. The dorsal fin (about 19 rays) originates about midway of the length of the fish, opposite the vent, and runs backward over three and one-half rings to within half a ring of the commencement of the tail sector of the trunk. The very small anal fin stands opposite the rear part of the dorsal fin. The pectorals are of moderate size, broad based and round tipped; it has no ventral fins and no caudal fin. Color— Light brown or dusky to ashen gray or yellow, variously mottled and blotched with paler and darker, sometimes spangled with silver dots, sometimes plain colored. European sea horses change color according to their surroundings, tints of red, yellow, brown, and white all being within their capabilities, and it is probable that the American species is equally adaptable. Size— Adults usually are 3 to 6 inches long; one of 7? inches is the largest on record.[84] Habits— Sea horses dwell chiefly among eelgrass and seaweed,[85] where they cling with their prehensile tails, monkeylike, to some stalk. They usually swim in a vertical position by undulations of the dorsal fin, not with the tail, the trunk being too stiff for much sidewise motion. Sea horses feed on minute Crustacea and on various larvae, in fact on any animal small enough, sucking in their prey as the pipefish does (p. 313.) They breed in summer[86] and the breeding habits resemble those of the pipefish, the male nursing the eggs in his brood pouch where they are deposited a few at a time by the female in repeated pairings. The young, of which there may be as many as 150, are about 10 to 12 mm. long at hatching. When the yolk sac is absorbed the father squeezes them out of the brood sac, and they already resemble the adult in general appearance within a few days after they are set free. According to some students they swim out and in at will, but this calls for verification. [page 316] General range— Atlantic Coast of North America, occurring regularly from South Carolina to Cape Cod, and to Nova Scotia as a stray. Occurrence in the Gulf of Maine— The sea horse is not common much beyond New York. Only a few are found each year about Woods Hole, chiefly in July, August, and September, and they so rarely stray past the elbow of Cape Cod that we have found only one definite (Provincetown) and one dubious (Massachusetts Bay) record of its capture in the inner parts of the Gulf of Maine, dead or alive; and one record for Georges Bank. Three specimens of the sea horse were also reported from Nova Scotia more than ? of a century ago;[87] and Vladykov and McKenzie have reported one, picked up in Terrance Bay, on the outer Nova Scotian coast, Sept. 18, 1934, by V. Slaunhite.[88] Good luck!

Seahorses are a genus of fish belonging to the family Syngnathidae, which also includes pipefish and leafy sea dragons. The seahorses are found in tropical and subtropical coastal and reef waters all over Pacific, Atlantic and Indian oceans. Seahorses range in size from 16 mm (the recently discovered Hippocampus denise[2]) to 35 cm. Seahorses and pipefishes are notable for being the only species in which males become "pregnant". The seahorse has a dorsal fin located on the lower body and pectoral fins located on the head near their gills. Some species of seahorse are partly transparent and are rarely seen in pictures. Sea dragons are close relatives of seahorses but have bigger bodies and leaf-like appendages which enable them to hide among floating seaweed or kelp beds. Seahorses and sea dragons feed on larval fishes and amphipods, such as small shrimp-like crustaceans called mysids ("sea lice"), sucking up their prey with their small mouths. Many of these amphipods feed on red algae that thrives in the shade of the kelp forests where the sea dragons live. Mating Seahorses reproduce in an unusual way: the male becomes pregnant. "The female inserts her ovipositor into the male’s brood pouch, where she deposits her eggs, which the male fertilizes. The fertilized eggs then embed in the pouch wall and become enveloped with tissues."[4] New research indicates the male releases sperm into the surrounding sea water during fertilization, and not directly into the pouch as was previously thought.[5] Most seahorse species' pregnancies lasts approximately two to three weeks. Hatched offspring are independent of their parents. Some spend time developing among the ocean plankton. At times, the male seahorse may try to consume some of the previously released offspring. Other species (H. zosterae) immediately begin life as sea-floor inhabitants (benthos). Seahorses are generally monogamous, though several species (H. abdominalis among them) are highly gregarious. In monogamous pairs, the male and female will greet one another with courtship displays in the morning and sometimes in the evening to reinforce their pair bond. They spend the rest of the day separate from each other hunting for food.|||||http://en.wikipedia.org/wiki/Seahorse|||||Any of a number of species of small marine fishes of the family Syngnathidae (order Gasterosteiformes), found in warm seas.
