This small fish is smoother than some of its seahorse counterparts, but still displays a variety of colors and the ability to change color quickly for camouflage.
It is a poor swimmer that prefers to ambush small prey from its secure hiding spot among seagrass, mangroves, or gorgonian coral, quickly sucking them into its toothless snout. They mate for life, have complicated courtship and bonding rituals, and the male carries the embryos to term in his brood pouch. These longsnout seahorses grow to almost 7 inches long and live one to four years.
They have few predators because of their camouflage and bony-plated body, but are collected by humans for the aquarium trade or folk medicine. English language common names for this species include longsnout seahorse, Brazilian seahorse, seahorse, and slender sea horse.
The longsnout seahorse is considered an important species in the aquarium trade and is one of the most exported Brazilian marine ornamental fish species. In addition, it is commonly collected for use in folk medicine, as souvenirs, and for religious purposes.
This seahorse is also frequently taken as bycatch in non-selective fishing gear such as trawl nets. Many seahorse populations are declining due to unsustainable exploitation of these unusual fish.
They are collected as aquarium fish, folk medicine, curiosities and for religious purposes. Seahorses are also taken as bycatch in the shrimp trawl fisheries off the coasts of the US, Mexico, and Central America.
In particular, the longsnout seahorse is considered threatened in hlppocampus US by the American Fisheries Society due to the rarity of this species along with degradation of its seagrass habitats in South Florida. Typically the longsnout seahorse is considered an uncommon uippocampus although in some locations it may be common.
It is usually observed attached to mangroves, seagrasses or gorgonians, however it may also be seen swimming freely in the midwater or associated with floating sargassum.

During the night, this species stops feeding and also stops swimming, wrapping its tail around a holdfast and remaining there until dawn. Seahorses swim by rapid undulations of the dorsal and pectoral fins. The depth range of this seahorse is meters with smaller individuals residing in shallower habitats. Male longsnout seahorses typically have a smaller home range than do the females, this is thought to be due at least in part to lower mobility due to the brood pouch.
Distinctive Features This seahorse has a narrow body with a long thick snout. The coronet crown-shaped piece of skin located at the top of the head may be quite large, rounded and convoluted. Tubercles are low and rounded while spines are absent with the exception of eye spines. Typically there are no skin appendages, although the longsnout seahorse is covered with rings of bony plates.
The tail is long and curved. Coloration The longsnout seahorse ranges from black to yellow, red, orange and brown with numerous white dots primarily on the tail. Pale saddles may be present along the dorsolateral surfaces. A interesting aspect of seahorse coloration is the ability to rapidly transform color patterns to blend with their immediate surroundings.
This species is similar to the lined seahorse H. It also has a deeper body and a wedge-like or triangular coronet with sharp edges and spines while the longsnout seahorse has a narrower body and a rounded coronet. Size, Age, and Growth Seahorses generally live from one to four years. The maximum reported size of the longsnout seahorse is 6.
This species reaches maturity at approximately 3. Food Habits The diet of the longsnout seahorse consists of ghost shrimp, grass shrimp, opossum shrimp, amphipods, and other small marine crustaceans. When feeding, seahorses use their long snout and small mouth to create pipette-like suction drawing live prey into their hippocampux.
Longsnout seahorses search for prey only during day light hours. They do not have teeth, food is swallowed whole, passing quickly through the digestive system. Reproduction The ovoviviparous longsnout seahorse is pair-bonded in the wild, in other words, males mate for life with the same female.
Breeding season extends for at least eight months out of the year with hipppcampus reports documenting this species as actively reproducing year-round with a peak from October to February.
Slender seahorse – Wikipedia
Courtship behavior includes the male impressing the female with dramatic hippocajpus in coloration, pouch displays, and graceful swimming behaviors. The female will deposit up to 1, eggs in the males pouch where fertilization takes place. Seahorse eggs are oval or pear-shaped, orange in color, and measure 0.
The pouch seals shut during egg development, opening approximately 14 days later when the eggs hatch and the male gives birth to tiny young seahorses that appear identical to mature seahorses.
Newborn seahorses measure approximately 0. Predators In general, seahorses are believed to have few natural predators due to their ability to camouflage along with their unpalatable boney plates and spines.
Even so, seahorses have been documented from the stomachs of large pelagic fishes including red snapper, dorado, rays, skates, tuna, and dolphinfishes. Parasites External parasites of seahorses include flukes, isopods, and monogenetic trematodes; internal parasites are digenetic trematodes, cestodes, and nematodes.
The longsnout seahorse was originally described by Ginsburg as Hippocampus reidi in Synonyms found in scientific literature referring to this species include H. This fish belongs to the family Syngnathidae which includes pipefish and leafy sea dragons. Discover Fishes Hippocampus reidi.
