Jaws protrusible. Gill filaments lobelike and with tufts. Opercle and subopercle very small. Preopercle very much enlarged. Dorsal and anal fins short, spineless and usually with 5 soft rays each. Relatively large and horizontal pectoral fins; unbranched rays 10-18. Pelvics abdominal; spine 1; soft rays 1-3. Caudal fin rays 8; the peduncle quadrangular. Branchiostegal rays 5; filamentous. No supracleithrum and post cleithrum. Circumorbital bones 3; lachrymal bone the largest. Swimm bladder absent. Vertebrae 19-22, first 6 abdominal vertebrae elongated. About 13 cm maximum length.

Pegasidae

This article is about a scientific family of fishes. For the mythological Greek nymphs, see Pegasides.

The seamoths make up a family of fishes, the Pegasidae, within the order Gasterosteiformes. They are named for Pegasus, a creature from Greek mythology. Seamoths are notable for their unusual appearance, including flattened bodies, the presence of large, wing-like, pectoral fins, a long snout, and a body encased in thick, bony plates. They are found primarily in coastal tropical waters of the Indo-Pacific.[1]

Biology[edit]

Seamoths have modified pelvic fins that allow them to "walk" across the sea bottom where they live. Their jaws are ventral, located behind their long rostrum, and are toothless. Their mouth is highly specialized, and can form a tube-like mouth used to suck worms and other small invertebrates from their burrows.[2] They periodically molt their bony external armor, perhaps as often as every five days.[3]

Conservation[edit]

Pegasus laternarius is listed as a Vulnerable species by the IUCN, while the remaining four species of seamoth remain Data Deficient. Threats to seamoths come from various sources, including fisheries where they are caught as bycatch or on purpose for use in traditional Chinese medicines. They are also collected for sale in the aquarium trade. Bottom trawls and coastal development may detrimentally alter habitat used by benthic seamoths. Life history characteristics such as low population sizes and monogamy with long-term pair bonding put them at risk of exploitation.[4][5][6][7][8]
