Yahoo! Answers - Home Seahorses, Seahorse Pictures, Seahorse Facts Seahorses are truly unique, and not just because of their unusual equine shape. Unlike most other fish, they are monogamous and mate for life. Rarer still, they are among the only animal species on Earth in which the male bears the unborn young. Found in shallow tropical and temperate waters throughout the world, these upright-swimming relatives of the pipefish can range in size from 0.6 inches (1.5 centimeters) to 14 inches (35 centimeters) long. Male seahorses are equipped with a brood pouch on their ventral, or front-facing, side. Because of their body shape, seahorses are rather inept swimmers and can easily die of exhaustion when caught in storm-roiled seas. They anchor themselves with their prehensile tails to sea grasses and corals, using their elongated snouts to suck in plankton and small crustaceans that drift by. Population data for most of the world’s 35 seahorse species is sparse.
Marine biology Only 29 percent of the world surface is land. The rest is ocean, home to the marine lifeforms. The oceans average nearly four kilometres in depth and are fringed with coastlines that run for 360,000 kilometres.[1][2] A large proportion of all life on Earth exists in the ocean. Marine life is a vast resource, providing food, medicine, and raw materials, in addition to helping to support recreation and tourism all over the world. Many species are economically important to humans, including food fish (both finfish and shellfish). History[edit] The observations made in the first studies of marine biology fueled the age of discovery and exploration that followed. The creation of marine labs was important because marine scientists had places to conduct research and process their specimens from expeditions. Subfields[edit] The marine ecosystem is large, and thus there are many sub-fields of marine biology. Related fields[edit] Animals[edit] Birds[edit] Fish[edit] Invertebrates[edit] Mammals[edit]
