沙毛

鰻鯰魚,俗稱沙毛,英文名是striped eel catfish。牠的外型類似土虱,體延長,頭部略平扁,腹部圓,後半部側扁,尾尖如鰻尾,頭中大,吻部略尖。口開於吻端略下方,口部附近有4對鬚,鼻鬚1對,上頜鬚1對,頦鬚2對,體表無鱗。第一背鰭短,前有堅強硬棘。第二背鰭及臀鰭與尾鰭連續相接,都是軟條。胸鰭位於頭部正後方,上緣具數枚銳利的硬棘,背鰭及胸鰭的第1根硬棘具有毒腺。體背側棕灰色,體側中央有兩條黃色縱帶,奇鰭的外緣黑色,體長可達20~30公分。

有少數鯰魚生活在珊瑚礁區,也常發現於潮池、河口域或開放性的沿岸海域。鰻鯰魚屬於群集性魚類,平常大多成群結隊活動,白天棲息在岩礁或珊瑚礁洞隙中,晚上才出來覓食,以小蝦或小魚為食,屬夜行性魚類。分布於臺灣南北岩礁區、日本、韓國、東印度群島、印度洋、紅海等地。

鰻鯰魚刺毒的化學性質並不清楚,根據研究至少有2種以上成分,一是神經毒性的polotospasmin,分子量約1萬,另一是溶血性的polotolysin,分子量約18萬。以鰻鯰魚刺毒素進行動物試驗,會發生肌肉痙攣收縮、呼吸困難、局部紅腫、壞死等現象。鰻鯰魚刺毒的中毒症狀,包括劇痛、麻痺、虛脫、休克等。此外,鰻鯰魚的皮膚也會分泌毒素,分子量大約1萬1千,在動物試驗中發現皮膚分泌的毒素具有溶血性及浮腫作用。但鰻鯰魚刺毒與皮膚分泌的毒素是否有關聯性,至今尚未明瞭。
