The species is sexually dimorphic and it is easy to distinguish between a male and female lined seahorse. The males are larger and also have longer tails. The lined seahorse is monogamous and performs ritual dances every morning to reestablish the bond with its mate. In addition, they create clicking sounds while embracing their partner.
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]
Pygmy seahorses have a single gill opening on the back of the head (instead of two on the sides as in normal seahorses), and the males brood their young inside their trunk, instead of in a pouch on the tail. [11] A molecular phylogeny confirms that the pygmy seahorses are a monophyletic sister lineage of all other seahorses. [10]
Like other seahorses, the dwarf seahorse has a head angled at right angles to its body and swims upright using its dorsal fin to propel it and its pectoral fins to steer. It grows to an average length of 2 and 2.5 cm (0.8 and 1.0 in), with a maximum length of 5.0 cm (2.0 in).

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]
H. kuda is a popular species among aquarium keepers. Common seahorses have very small mouths, eating only small animals like brine shrimp and even newborn guppies. Seahorses need to eat approximately 4–5 times daily. Many aquarists who have kept H. kuda cultivate their own brine shrimp and rotifers. Daphnia is eaten when other foods are ...
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 ...
