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.
Other small seahorses are sometimes called pygmy seahorses, but lack the single gill opening and trunk brooding that distinguish the true pygmy seahorse. They can be called dwarf seahorses: [5] Red Sea soft coral pygmy seahorse, Hippocampus debelius, endemic to the Red Sea; Bullneck seahorse, Hippocampus minotaur, from southeast Australia
A seahorse (also written sea-horse and sea horse) is any of 46 species of small marine bony fish in the genus Hippocampus. The genus name 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 ]
Denise's pygmy seahorse uses adaptive camouflage, changing its color to match that of the surrounding gorgonians. [4] It feeds on small crustaceans and other zooplankton. [6] An individual will stay on a single coral for the duration of its entire life. The species is ovoviviparous, and it is the male who broods the eggs in its ventral brood pouch.
The lined seahorse is a diurnal species that ranges in length from 12 cm to 17 cm; the maximum length reported for the species is 19 cm. The seahorse is sexually dimorphic, meaning there are distinct differences in appearances of males and females; most notably the brood pouch located on the male's abdomen which it utilized in reproduction.
Dwarf seahorse: The slowest-moving fishes are the sea horses. The slowest of these, the tiny dwarf seahorse, has a sprint speed of one inch per minute. [111] Atlantic bluefin tuna: The Atlantic bluefin tuna is capable of sustained high speed cruising, and maintains high muscle temperatures so it can cruise in relatively cold waters. Indo ...
Seahorses are a genus (Hippocampus) of fish belonging to the family Syngnathidae, which also includes pipefish and leafy sea dragons. There are over 32 species of seahorse, mainly found in shallow tropical and temperate waters throughout the world. They prefer to live in sheltered areas such as sea grass beds, coral reefs, or mangroves.
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]
