Urocampus nanus, also known as the barbed pipefish, is a species of marine fish belonging to the family Syngnathidae[1]. The species can be found inhabiting seagrass beds in sheltered shoreline and estuary habitats along the coasts of southern Japan and Korea.[2][3][4][5][6] Their diet likely consists of small crustaceans [7]. Reproduction occurs through ovoviviparity in which the males brood eggs for 11-16 days before giving live birth [3][8]. Urocampus nanus is thought to be polyandrous, where multiple females compete over breeding with a single male.[8]
