The long-snouted seahorse has a carnivorous diet and feeds on small crustaceans, larvae, fish eggs and other planktonic organisms.It is ovoviviparous and it is the male who broods the eggs in its ventral brood pouch. The latter includes villi rich in capillaries that surround each fertilized egg, creating a sort of placenta supplying the embryos.

These seahorses may have brown and white dots over their skin, which is a variety of colors, including black, yellow, red-orange, or brown. They may also have...
Kingdom: AnimaliaPhylum:ChordataClass:ActinopterygiiOrder:GasterosteiformesLongsnout seahorses are found in the western North Atlantic Ocean from North Carolina to Brazil. They are also found in the Caribbean Sea and Bermuda. They are found in relatively shallow water (0 to 180 feet) and are often attached to seagrasses, mangroves, and gorgonians or among floating Sargassum, oysters, sponges, or man-made structures. Femal...
Longsnout seahorses eat small crustaceans, plankton, and plants using their long snout with a pipette-like motion to suck in their food as it passes by. These animals feed during the day and rest at night by attaching to structures in the water such as mangroves or seagrasses.
Longsnout seahorses are sexually mature when they are about 3 inches long. Like other seahorses, they are ovoviviparous. This seahorse species mates for life. Seahorses have a dramatic courtship ritual in which the male may change color and inflate his pouch and the male and female perform a "dance" around each other. Once courtship is complete, th...
The global population of the species is listed as near-threatened on the IUCN Red Listas of an October 2016 assessment. One threat to this seahorse is harvest for use in aquariums, as souveniers, as medicinal remedies, and for religious purposes. They also are caught as bycatchin shrimp fisheries in the U.S., Mexico, and Central America and are thr...

Version 2014.2.The snout is both long and narrow, allowing the seahorse to easily extend it and reach small crustaceans, such as shrimp and copepods, that make up their primary food source. Additionally, the snout’s flexibility aids in capturing the larval fish and other small floating creatures that seahorses consume. Vacuum Feeding
The longsnout seahorse can be found at depths of 0-55 meters (0-180 feet); however, younger individuals tend to stay near shallow habitats. Longsnout seahorses generally have a narrow body, a long thick snout, and a crown-shaped piece of skin located at the top of the head known as a “coronet”. They have a low, round tubercle (outward ...
Longsnout seahorses are very poor swimmers and rely on camouflage and bony plates that cover most of their bodies to avoid predation. Like other seahorses, the longsnout seahorse’s tail is highly maneuverable, and it uses this tail to attach itself to seagrasses, mangrove roots, sponges, soft corals, or other places where it hides.

Measuring up to 25 centimetres, they are usually brownish, but can change colour very quickly for camouflage and during courtship. They inhabit shallow coastal ...
