Male seahorses have a specialized ventral brood pouch to carry the embryos, male sea dragons attach the eggs to their tails, and male pipefish may do either, depending on their species. [4] The most fundamental difference between the different lineages of the family Syngnathidae is the location of male brood pouch. [5]
The species is found in depths of water up to seventy-three meters. Adults can be found swimming freely in the water column or attached to a stationary object. Juveniles usually swim near the surface. [6] The habitat of the lined seahorse consists of marine vegetation, such as suspended Sargassum, seagrass, sponges, and mangroves.
A seahorse (also written sea-horse and sea horse) is any of 46 species of small marine bony fish in the genus Hippocampus. The genus name comes from the Ancient Greek hippókampos (ἱππόκαμπος), itself from híppos (ἵππος) meaning "horse" and kámpos (κάμπος) meaning "sea monster" [4] [5] or "sea animal". [6]

The short-snouted seahorse (Hippocampus hippocampus) is a species of seahorse in the family Syngnathidae. It is endemic to the Mediterranean Sea and parts of the North Atlantic, particularly around Italy and the Canary Islands. In 2007, colonies of the species were discovered in the River Thames around London and Southend-on-Sea. [4]
The Pacific seahorse, also known as the giant seahorse, (Hippocampus ingens) is a species of fish in the family Syngnathidae. Their genus name (Hippocampus) is derived from the Greek word hippos, which means "horse" and campus, which means "sea monster." [4] This species is the only seahorse species found in the eastern Pacific Ocean. [5]
Even excluding the trade demand for this species, it is known to often be bycatch in non-selective fisheries, for example, fish and shrimp trawls which occurs throughout the range of the species and leads to the degradation of the habitat for those seahorses. [9] Shrimp trawls are a major concern to the Hippocampus histrix species. Trade is ...
The head of the seahorse resembles a crown. Its spine is very prevalent, but has a rounded shape, especially above its eye. It is often confused for other species, and some great seahorses have even been thought to be an entirely new species, but gene sequencing has disproved this.
