Seahorses range in size from 1.5 to 35 cm (0.6 to 13.8 in). [13] They are named for their equine appearance, with bent necks and long snouted heads and a distinctive trunk and tail. Although they are bony fish, they do not have scales, but rather thin skin stretched over a series of bony plates, which are arranged in rings throughout their bodies.
The fins help guide and propel the seahorse. Lined seahorses are weak swimmers; they swim in an erect position. In comparison to their fins, the lined seahorse's body is too large, another reason why they are poor swimmers. They do not swim for long periods of time, nor do they travel far distances, unless they are migrating. [11]
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 dwarf seahorse (Hippocampus zosterae) is a species of seahorse found in the subtidal aquatic beds of the Bahamas and parts of the United States. It is threatened by habitat loss . According to Guinness World Records , it is the slowest-moving fish, with a top speed of about 5 feet (1.5 m) per hour.
They have a prominent spine above each eye. They have snouts that are short and upturned. [9] Their snouts are about 1/3 of the length of their head. [10] Their dorsal fin has 16–18 rays with a dark stripe that runs parallel to the margin and provides propulsion. Their pectoral fins have 13–15 rays and are located below the gill openings.

Typically found in waters less than 50 m (160 ft) deep, they have been observed at depths as great as 104 m (340 ft) [8] Notably, this is the largest seahorse species in southeastern Australia, with more dorsal fin rays and tail rings than any other seahorse.
The Knysna / ˈ n aɪ z n ə / seahorse or Cape seahorse (Hippocampus capensis) is a species of fish in the family Syngnathidae. [3] It is endemic to the south coast of South Africa, where it has been found in only three brackish water habitats: the estuary of the Keurbooms River in Plettenberg Bay, the Knysna Lagoon, and the estuarine portion of the Swartvlei system in Sedgefield.
