簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 0; 背的軟條 (總數): 0; 臀棘 0; 臀鰭軟條: 0. No true fins - one dorsal finfold, far back, median, very low, continuous with caudal; caudal broad, rounded; ventral finfold very low, origin somewhat posterior to last gill pore, extending to anus (Ref. 6885). Dark brown, tan, gray, or brownish red, often tinted with blue or purple, never black, lighter ventrally, rarely with large patches of white; preserved specimens light brown (Ref. 6885).
沒有真實的鰭 - 一背部的鰭褶, 遠在背上﹐中央的﹐和非常低的, 與尾部的續接在一起; 尾部的寬, 圓的; 腹面鰭褶非常低的, 起源略微在被延伸至肛門的最後的鰓孔後面.(參考文獻 6885) 深褐色的﹐黃褐色的﹐灰色的﹐或紅褐色的, 時常帶有了藍色或者紫色, 從不黑色的﹐腹部顏色較淡, 很少有白色的大區塊; 保存的標本淡褐色.(參考文獻 6885)

生物學特性     字彙 (例如 epibenthic)

Inhabits fine silt and clay bottoms (Ref. 6885). Enters large fishes by way of the mouth and anus and feed on its viscera and muscles (Ref. 6885). May greatly diminish catches taken with fixed gears (Ref. 6885). Produces mucilaginous slime when harassed (Ref. 6885). Probably exhibits hermaphroditism (Ref. 56947). Due to its primitive metabolism it is collected for research purposes (Ref. 6885).

棲息於細沙與泥土底部。 (參考文獻 6885) 經由嘴與肛門進入大魚體內並且吃它的內臟與肌肉。 (參考文獻 6885) 可能急遽的減少捕獲用定置網採集了。 (參考文獻 6885) 被攻擊時會分泌黏稠的黏液.(參考文獻 6885) 由於它的原始代謝作用它被為研究目的而收集。 (參考文獻 6885)

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

Copulatory organ absent (Ref. 51361). Presence of bisexual juvenile gonad, requires further investigation regarding hermaphroditism (Ref. 56947). In one study (Ref. 40710), hermaphroditism is exhibited by only 0.2% of the individuals studied.東太平洋: 從阿拉斯加州東南方到 Bahia San Pablo, 中央的墨西哥的下加利福尼亞。
