A seahorse (also written sea-horse and sea horse) is any of 46 species of small marine bony fish in the genus Hippocampus. "Hippocampus" 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 lined seahorse (Hippocampus erectus), northern seahorse or spotted seahorse, is a species of fish that belongs to the family Syngnathidae. [3] [4] H. erectus is a diurnal species with an approximate length of 15 cm (5.9 inches) and lifespan of one to four years.
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]
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 name paradoxus was given because the seahorse is very different from all of the other members of genus Hippocampus; the seahorse is paradoxical. [3] It is most closely related to another seahorse, H. minotaur. Like all seahorses, this species is sexually dimorphic. It is theorized that the brood pouch is attached on the ventral side ...
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 horizon dates 13 million years back to the lower Sarmatian during the middle Miocene period, making the two species the earlier known seahorse fossils in the world. Among the remains, one adult female specimen is fully preserved, with bony plates and other important macroscopic features.
Denise's pygmy seahorse is a small fish which can reach a maximum length of approximately 2.4 cm, which makes it one of the smallest representatives of the seahorses. [4] This pygmy seahorse has a short snout, slender body with a prehensile tail.
