Most pygmy seahorses are well camouflaged and live in close association with other organisms including colonial hydrozoans (Lytocarpus and Antennellopsis), coralline algae , and sea fans (Muricella, Annella, and Acanthogorgia). This combined with their small size accounts for why most species have only been noticed and classified since 2001.
Hippocampus kuda is a species of seahorse, also known as the common seahorse, estuary seahorse, yellow seahorse or spotted seahorse. The common name sea pony has been used for populations formerly treated as the separate species Hippocampus fuscus , now a synonym of H. kuda .
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 of Idiotropiscis are more seahorse-like in appearance in having a deeper body and discontinuous superior trunk and tail ridges. [7] The main differences between this pygmy pipehorse genus and the seahorses is that the latter have an upright posture, and the angle of their head relative to the abdominal axis is greater.
This Pygmy seahorse was founded by Dr.Graham Short and his colleagues who attend the California Academy of Sciences. They represent the fifth species of Pygmy seahorse that has been recorded in Japan. [19] Sodwana pygmy seahorse (Hippocampus nalu) is the second most recently described species. [20]
In addition to temperature, there is also a large range of salinity concentration depending on the location that affect the species. The most common salinity is 25 to 35 ppt. In captivity, the species is most commonly kept at 35 ppt. [10] The H. erectus is the only species of seahorse native to the Chesapeake Bay. [11]
[2] [3] [4] The Korean seahorse is the most common seahorse in Korean waters so that the scientific name 'haema' is named from 'seahorse' in Korean. The Japanese name 'Himetatsu' is derived from its smaller shape such as body and coronet rather than the shape of a sister species, crowned seahorse (Hippocampus coronatus).
In both Brazil and Argentina, seahorses are collected and traded as curios, traditional medicines, religious amulets and as aquarium fishes. H. patagonicus is the most commonly caught seahorse species in the south and southeast regions of Brazil, usually as by-catch of shrimp fisheries. Habitat degradation by coastal urban development, shrimp ...
