生態學
海洋; 半鹹淡水 礁區魚類; 非產卵性溯降河的 (Ref. 51243); 深度上下限 1 - 60 m (Ref. 37816). 熱帶; 38°N - 35°S, 20°E - 169°W
Indo-Pacific: Red Sea and East Africa to Samoa, north to southern Japan, southern Korea, and the Ogasawara Islands, south to Australia and Lord Howe Island. Palau and Yap in Micronesia (Ref. 1602). Sometimes enters freshwaters of East Africa (Lake Malawi) and Madagascar (Ref. 3879). First record in the Mediterranean (Ref. 123740),
印度-太平洋: 紅海而且東非到美屬薩摩亞, 北至日本南部，韓國南部, 與小笠原群島南至澳洲與羅得豪島。 密克羅尼西亞的帛琉與雅普島.(參考文獻 1602) 有時進入東非 (馬拉威湖) 與馬達加斯加的淡水。 (參考文獻 3879)
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 16.9 range ? - ? cm
Max length : 35.2 cm TL 雄魚/尚未辨別雌雄; (Ref. 127810); common length : 25.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 3478); 最大年齡: 7 年 (Ref. 240)
背棘 (總數) : 1; 背的軟條 (總數) : 69 - 115; 臀棘: 0; 臀鰭軟條: 58 - 82. This species has the dorsal and anal fins continuous with caudal fin; with 4 pairs of mouth barbels; and a single highly venomous serrate spine at the beginning of the first dorsal and each of the pectoral fins (Ref. 1602).
背鰭與臀鰭與尾鰭續接在一起。 四對嘴觸鬚。 在第一背鰭與每一根胸鰭的起點一根強烈毒性的鋸齒狀的棘.(參考文獻 1602)
Coastal benthic (Ref. 68964). The only catfish found in coral reefs. Also found in estuaries, tide pools and open coasts. Juveniles form dense ball-shaped schools of about 100 fish; adults are solitary or occur in smaller groups of around 20 and are known to hide under ledges during the day (Ref. 1602, 5503, 12693, 37816, 48635). Adults search and stir the sand incessantly for crustaceans, mollusks, worms, and sometimes fish (Ref. 5213). Oviparous, with demersal eggs and planktonic larvae (Ref. 205). The highly venomous serrate spine of the first dorsal and each of the pectoral fins are dangerous, and even fatal in rare cases (Ref. 1602).
珊瑚礁中唯一的鯰魚。 也發現於河口，潮池與開放的海岸。 稚魚形成密集的球-大約 100個魚的形狀魚群; 成魚是獨居性的或者出現在比較小的群體大約 20 而且被知道躲藏在岩架下在白天期間.(參考文獻 1602,5503,12693,37816,48635) 成魚不斷地攪動砂搜尋甲殼動物，軟體動物，蠕蟲, 與有時魚.(參考文獻 5213) 卵生的，具有沉性卵與浮游生物仔魚.(參考文獻 205) 第一背鰭的強烈毒性鋸齒狀棘與每一根胸鰭是危險的, 甚至在少數情況下會致命.(參考文獻 1602)

The male in the spawning pair constructs the nest under rocks and other large pieces of debris (Ref. 240). After spawning, the female departs while the male guards the eggs.印度-太平洋: 紅海而且東非到美屬薩摩亞, 北至日本南部，韓國南部, 與小笠原群島南至澳洲與羅得豪島。 密克羅尼西亞的帛琉與雅普島.(參考文獻 1602) 有時進入東非 (馬拉威湖) 與馬達加斯加的淡水。 (參考文獻 3879)
