A seahorse 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" or "sea animal". Having a head and neck suggestive of a horse, seahorses also feature segmented bony armour, an upright posture and a curled prehensile tail. Along with the pipefishes and seadragons they form the family Syngnathidae.

The specific name honours Michitaro Sindo, who was originally from Yamaguchi and who was assistant curator of fishes at Stanford University.
The rougheye rockfish is a rockfish of the genus Sebastes. It is also known as the blackthroat rockfish, rougheye seaperch, blacktip seaperch, longlife seaperch or the blacktip rockfish and grows to a maximum of about 97 cm (38 in) in length, with the IGFA record weight being 14 lb 12 oz (6.7 kg). Similar to many other members of its genus, it is extremely long-lived, and has been known to reach an age of 205 years.
Pterois sphex, the Hawaiian turkeyfish or Hawaiian lionfish is a species of ray-finned fish with venomous spines belonging to the family Scorpaenidae, the scorpionfishes and lionfishes. It is found in the eastern Central Pacific, specifically in marine waters off of Hawaii. It is found in seaward reefs and lagoons at depths from 3 – 122 m.
Liparis liparis, the common seasnail, striped seasnail or seasnail, is a small species of marine ray-finned fish belonging to the family Liparidae, the snailfishes, in the order Scorpaeniformes, the scorpionfishes and flatheads.

The barchin scorpionfish is a species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. It comes from the Indo-Pacific. The species is commonly seen in areas with mixed sand and rubble in reef flats, shallow lagoons, and channels.
Mugil thoburni, Thoburn's mullet, is a species of grey mullet, from the family Mugilidae, found in the eastern Pacific Ocean. It is most common around the Galapagos Islands but does occur on the coasts of Central America and South America as well. This species grows to a length of 29.5 centimetres (11.6 in) TL. It was formerly regarded as the only known member of the genus Xenomugil.
The deep-bodied pipefish is a species of marine fish belonging to the family Syngnathidae. They can be found in shallow estuaries and algal beds along the coast of South America from Ecuador to Argentina. Predators of this species include mackerel and the La Plata dolphin. Reproduction occurs through ovoviviparity: the eggs are carried in a pouch under the tail of the male until they hatch.
Coleman's pygmy seahorse is a species of fish of the family Syngnathidae. It is found off of the coast of Lord Howe Island, Australia, although unconfirmed occurrences have been reported from Milne Bay and the Ryukyu Islands. It lives in coarse sand and Zostera and Halophila sea grasses at depths around 5 metres (16 ft). It is expected to feed on small crustaceans, similar to other seahorses. Ovoviviparous reproduction is also expected, with males brooding eggs in a pouch before giving birth to live young.
Pristipomoides auricilla, the goldflag jobfish or the yellow flower snapper, is a species of ray-finned fish, a snapper belonging to the family Lutjanidae. It is found in the Indo-Pacific region.
Edmondson's pipefish is a species of marine fish of the family Syngnathidae. It is endemic to coastal waters of the Hawaiian Islands, from Oahu to Maui, where it inhabits shallow reefs, beaches and tidepools to depths of 33 metres (108 ft). Although this species' feeding habits are unknown, it is expected to feed on small crustaceans similar to other pipefishes. This species is ovoviviparous, with males carrying eggs in a brood pouch before giving birth to live young. Males may brood at 9.4 centimetres (3.7 in).
Gray's pipefish, also known as the mud pipefish or spiny pipefish is a species of marine fish of the family Syngnathidae. It is found in the Indo-Pacific in the Gulf of Aden, Sri Lanka, and from the Gulf of Thailand to Japan, the Marshall Islands, and the Great Barrier Reef. It lives to depth of 100 metres (330 ft), and planktonic juveniles have been found above depths of 3,000 metres (1.9 mi). It occurs in muddy habitats, in estuaries, and on coral reefs, where it likely feeds on small crustaceans. It can grow to lengths of 20 centimetres (7.9 in). This species is ovoviviparous, with males carrying eggs in a brood pouch before giving birth to live young.
Walter Kenrick Fisher was an American zoologist, evolutionary biologist, illustrator, and painter. He taught in Stanford University before eventually becoming Emeritus Professor in Zoology until his retirement in 1943. Fisher was the son of ornithologist Albert Kenrick Fisher.
Oliver Peebles Jenkins was an American physiologist and histologist, mainly associated with Stanford University.
Minyichthys myersi, also known as Myer's pipefish, is a species of marine fish belonging to the family Syngnathidae. They can be found inhabiting coral in many areas of the Indo-Pacific including Mauritius, Indonesia, the Philippines, Papua New Guinea, and French Polynesia. Their diet likely consists of small crustaceans such as copepods and amphipods. Reproduction occurs through ovoviviparity in which the males brood eggs before giving live birth.
