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]
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 ]
Many seahorse species are monogamous as mating occurs between the same two partners in one breeding season. However, the mating habits for H. guttulatus are unknown. [ 12 ] An interesting aspect of seahorse coloration is the ability to rapidly transform color patterns to blend with their immediate surroundings.
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.
They are some of the smallest seahorse species in the world, typically measuring less than 2 centimetres (0.79 in) in height. [1] [2] The first pygmy seahorse known to science was Hippocampus bargibanti. At least six more species were named after 2000. The first species discovered lives exclusively on fan corals and matches their colour and ...

Many are very weak swimmers in open water, moving slowly by means of rapid movements of the dorsal fin. Some species of pipefish have prehensile tails, as in seahorses . The majority of pipefishes have some form of a caudal fin (unlike seahorses), which can be used for locomotion. [ 2 ]
