While seahorses look very unique, they are related to other bony fish like cod, tuna and ocean sunfish. Identifying seahorses can sometimes be confusing, because many can be a variety of colors and they are also camouflage artists, capable of changing their color to blend in with their surroundings.
Currently, there are 47 recognized species of seahorses. This article gives a sampling of some of these species, including some most common in the United States. There is basic identification and range information in each description, but if you click on the seahorse name, you'll find a more detailed species profile.What's your favorite seahorse species?

Big-Bellied Seahorse (Hippocampus abdominalis)
The big-bellied, big-belly or pot-bellied seahorse is a species that lives off Australia and New Zealand. This is the largest seahorse species - it is capable of growing to a length of 14 inches (this length includes its long, prehensile tail). Characteristics used to identify this species are a big belly on the front of their body which is more pronounced in males, a large number of rings (12-13) on their trunk and tail (at least 45 rings), and coloration that includes dark spots on their head, body, tail and dorsal fin and bands of light and dark on their tail.
The longsnout seahorse is also known as the slender or Brazilian seahorse. They can grow up to about 7 inches long. Identifying features include a long snout and slender body, a coronet on their head that is low and convoluted, skin that may have brown and white dots or a pale saddle on their back. They have 11 bony rings around their trunk and 31-39 rings on their tail. These seahorses are found in the western North Atlantic Ocean from North Carolina to Brazil and in the Caribbean Sea and Bermuda.

Pacific Seahorse (Hippocampus ingens)
Although it's not quite the biggest seahorse, the Pacific seahorse is also known as the giant seahorse. This is a West Coast species - it is found in the Eastern Pacific Ocean from California south to Peru and around the Galapagos Islands. Identifying features of this seahorse are a coronet with five points or sharp edges at its top, a spine above their eye, 11 trunk rings and 38-40 tail rings. Their coloration varies from reddish to yellow, gray or brown, and they may have light and dark markings on their bodies.
Like many other species, the lined seahorse has a couple other names. It is also called the northern seahorse or the spotted seahorse. They may be found in cooler waters and live in the Atlantic Ocean from Nova Scotia, Canada to Venezuela. Notable features of this species are a coronet that is ridge- or wedge-shaped that has spines or sharp edges. This short-snouted seahorse has 11 rings around its trunk and 34-39 rings around their tail. They may have fronds projecting from their skin. Their name came from the white lines that sometimes occur along their head and neck. They also may have white dots on their tail and a lighter saddle coloration on their dorsal surface.

Dwarf Seahorse (Hippocampus zosterae)
As you could likely guess, dwarf seahorses are small. The maximum length of the dwarf seahorse, also known as the little or pygmy seahorse, isjust under 2 inches. These seahorses live inshallow waters in the western Atlantic Ocean in southern Florida, Bermuda, the Gulf of Mexico, and the Bahamas. Identifying characteristics of dwarf seahorses include a high, knob- or column-like coronet, mottled skin that is covered in tiny warts, and sometimes filaments extending from their head and body. They have 9-10 rings around their trunk and 31-32 around their tail.

Common Pygmy Seahorse (Bargibant's Seahorse, Hippocampus bargibanti)
The tiny common pygmy seahorse or Bargibant's seahorse is even smaller than the dwarf seahose. Common pygmy seahorses grow to less than an inch in length. They blend in well with their favorite surroundings - soft gorgonian corals. These seahorses live off Australia, New Caledonia, Indonesia, Japan, Papua New Guinea and the Philippines. Identifying features include an extremely short, almost pug-like snout, a rounded, knob-like coronet, the presence of large tubercles on their body, and a very short dorsal fin. They have 11-12 trunk rings and 31-33 tail rings, but the rings are not very noticeable.

Seadragons
Seadragons are Australian natives. These animals are in the same family as seahorses (Syngnathidae) and share some characteristics, including a fusedjaw and tubelike snout, slow swimming speed and ability to change color to camouflage. There are two types of seadragons - weedy or common seadragons and leafy seadragons.
Seahorses. Classification: Kingdom: Animalia, Phylum: Chordata, Class: Osteichthyes, Order: Gasterosteiformes, Family: Syngnathidae, Genus: Hippocampus, and many species. Seahorses are a marine fish belonging to the genus Hippocampus of the family Syngnathidae.
There are 46 recognised species of seahorses. Given their superior camouflage and the subtle differences between some species, taxonomists have long struggled on delineating and identifying them based on appearance alone.
The Knysna seahorse is the worlds most elusive and endangered seahorse. This species is only found across three fragmented, local estuaries on the south coast of South Africa. Threatened with extinction and is now totally protected by law.
In seahorses and pipefish, it is the male that gets pregnant and gives birth. Seahorse fathers incubate their developing embryos in a pouch located on their tail. The pouch is the equivalent of the uterus of female mammals.
bargibanti. Here is the pygmy bargibanti seahorse (Hippocampus bargibanti, also named seahorse pygmy gorgonians). It most often has small bumps of pink-purple or yellow-orange color. A purple bargibanti hippocampus poses on its gorgonian branch. ( Triton Bay, West Papua, Indonesia, March 2016)
The largest seahorse species (pictured here) is Hippocampus abdominalis , or the big-bellied seahorse, which can reach more than a foot long (35 cm) and lives in the waters off Southern Australia and New Zealand.
The 300 or so species often have limited ranges in coastal regions and freshwater lakes and rivers around the world, and many require specialized habitats, making them susceptible to disturbance. As a result, researchers found, at least 6% of these species and up to 38% are threatened and at some risk of extinction.
Seahorses are not one of those animals who change their sex. The female lays the eggs and the male carries the fertilized eggs on his back. They remain male and female.
A baby seahorse is called a “fry.” When the time is right for the babies to be born, the males will bend their bodies back and forth until a tiny seahorse pops out of the pouch.
A male seahorse can give birth to up to 2,000 babies in one delivery. This astonishing fact makes the seahorse one of the fastest-reproducing animals. Glioblastoma is one of the fastest-reproducing, aggressive brain tumours – and The National Brain Appeal want to fund new ways to treat it.
Walea soft coral pygmy seahorse (Hippocampus waleananus) lives on and around soft coral. The soft coral have fat stems and this seahorse has a correspondingly long tail. They vary from pale pink to yellow.
denise can live on different types of gorgonian genera. After choosing a seafan to live on the baby pygmy gets its final color which can range from yellow to orange or pink and body texture adapting to its new house. It grows to a maximal size of 24 mm.
Seahorses are tiny fish that are named for the shape of their head, which looks like the head of…. yup, you guessed it -a tiny horse. There are around 36 seahorse species, which are found in tropical and temperate coastal waters where they swim upright among seaweed and other plants.
Lined Seahorse are members of the fourth trophic level. Their niche is an ambush predator feeding on small crustaceans including shrimp, mollusks and zooplankton.
Seahorses go through six different stages throughout their life cycle and unlike humans the male seahorse is the one who gets pregnant and has the babies. Draw in the arrows to show the direction of the stages in the life cycle.
