顏色活著時可變的; 身體通常淡色到深褐色的, 有背部的與側面的區域比腹面顏色更深。 胸鰭透明又末梢部的邊緣白色與有斑點的。 腹鰭棘與第一鰭條形成細長又觸絲的結構。 三對體背外側的碟; 四對體腹外側的碟; 尾環 8(很少地 9), 移動的。 一對深的窪凹在眼窩後面。 眶下架凹曲, 眼看得見的由腹面觀之。 喙的腹面脊非常擴大了勝於背部的脊,每個具有朝向側面的細齒。 肛門的乳突不存在。
Inhabit lagoons often among algal or seagrass beds (Ref. 5503). Found on sand or silt bottoms, frequently in bays or estuaries (Ref. 3132). They are opportunistic feeders that collect mainly epifaunal and interstitial invertebrate prey, e.g., crustaceans and worms from the sediment-water interface (Ref. 31134). Shed their skin in one piece with a rapid jump periodically to rid themselves of accumulated ballast (Ref. 31134). Adults usually in pairs on muddy substrates (Ref. 48635). Has a monogamous mating system with close-pair bonding (Ref. 90102).
棲息於潟湖常見於海藻或海草床之中.(參考文獻 5503) 棲息於沙子或淤泥底了, 時常在海灣或河口.(參考文獻 3132) 他們是主要採集表生種而間質的無脊椎動物獵物，例如 , 甲殼動物與蠕蟲從沉澱物-水的介面的隨機捕食者。 (參考文獻 31134) 在一塊中脫落他們的皮膚用一個週期性的快速跳躍累積的壓載物免除他們自己。 (參考文獻 31134) 在泥質底部上成魚通常成對出現。 (參考文獻 48635)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Are broadcast spawners. In several aquaria, spawning is observed as pairs rose to about 50 cm above the substrate, their ventral surfaces closely opposed, releasing gametes at the apex of their upward rush; then they glided down to the bottom. As the pairs landed on the substrate, the male continued to follow his mate. Release of gametes follows. Spawning occurred only within pairs (obligate and genetic monogamy) (Ref. 52884).印度-太平洋: 對馬貴斯群島與社會群島的紅海與南非 (參考文獻 4264), 北至日本南部, 南至澳洲與羅得豪島; 在密克羅尼西亞各處。
