The external anatomy of female and male seahorses differ, a characteristic that is called sexual dimorphism. On the female seahorse, the lower abdomen joins the tail at a sharp angle and her anal fin is often higher and slightly larger. On males, a brood pouch is found beneath the anal fin, and when empty, tapers gradually to the tail.

All seahorses have independently orbital eyes and a pair of pectoral fins immediately behind the gill opening. The seahorses means of propulsion (process of propelling) are its pectoral fin, located just behind the gill opening and its dorsal fin, which joins the trunk at the tail.
The armor of bony plates also protects them against predators, [15] and because of this outer skeleton, they no longer have ribs. [16] Seahorses swim upright, propelling themselves using the dorsal fin, another characteristic not shared by their close pipefish relatives, which swim horizontally. Razorfish are the only other fish that swim ...

Seahorse sizes vary depending on the species. Their height ranges from the large Australian big-bellied seahorse, measuring about 11.8 inches or more in height, to a tiny pygmy seahorse, measuring less than an inch in height. Their weights vary depending on species, age and reproductive stage. A seahorse typically weighs between 7 ounces to 1 pound...
Seahorses have a distinct appearance that appears to be a fusion of multiple animals with a horse-like head, monkey-like tail, and kangaroo-like pouch. Only male seahorses have a brood pouch. Their eyes are like a chameleon in that they can move independently of each other and in all directions. Also like a chameleon, seahorses are masters of camou...
Seahorses mainly eat small crustaceans like amphipods and other invertebrates. Adult seahorses eat 30 to 50 times a day if available. They do not have a stomach or teeth, instead, they suck their prey in through a tubular snout, or a fused jaw, and pass it through an inefficient digestive system.
All seahorses are marine species. They are typically found in seagrass beds, mangrove roots, and coral reefs, in shallow temperate and tropical waters. Some species can also be found in estuaries, as they are able to tolerate wide ranges in salinity. In winter, some seahorse species move to deeper waters to escape the rough weather.
While it was long believed that seahorses mate for life, further research has shown that pair bonding is just for a few months at a time, or during the mating season. They reinforce their pair bonding with an elaborate courtship display, typically consisting of a color change. The female meets the male in his territory and as they approach each oth...
Like most fish species, seahorses do not nurture their young after birth. The infants are at risk of predators or ocean currents, which wash them away from feeding grounds or into temperatures too extreme for their delicate bodies. They have a survival rate of less than 0.5%. Seahorses are largely solitary creatures, aside from mating. Most species...
The lifespans of wild seahorses are unknown due to a lack of data. In captivity, lifespans for seahorse species range from about one year in the smallest species to three to five years in the larger species.
Seahorses are hunted by humans to be used for medicine, as souvenirs, and in the pet trade. They are used for all types of medicine. Traditional Chinese Medicine Trade takes in excess of up to 150 million seahorses a year from the wild. The Curio Trade also takes about one million seahorses from the wild. They are often sold as souvenirs. The pet t...
According to the International Union for Conservation of Nature (IUCN) Red List of Threatened Species, 12 of the 42 seahorse species that have been assessed so far are listed as Vulnerable, with two listed as Endangered, one as Near Threatened and 10 as Least Concern. The remaining 17 seahorse species are listed as Data Deficient.
Numerous conservation groups, such as Project Seahorse and The Seahorse Trust, are working to protect seahorse species. Further research is needed to assess and protect these species. Sources: Project Seahorse and The Seahorse Trust.
Sep 5, 2023 · Firstly, it is important to understand the basic anatomy of a seahorse. Seahorses belong to the family Syngnathidae, which also includes pipefish and sea dragons. They have a long, slender body with a distinct head and a curled tail. Unlike most fish, seahorses swim in an upright position, using their dorsal fin to propel themselves through the ...

Sep 5, 2024 · Seahorses are rather immobile, swimming more slowly than other fishes. When swimming they maintain a vertical position and propel themselves forward using a soft-rayed dorsal fin. They use pectoral fins located on the side of the head to maneuver.
