Environment: milieu / climate zone / depth range / distribution range 生態學

Western Indian Ocean: restricted to the Red Sea and the tropical western Indian Ocean to South Africa. Also reported from Persian Gulf (Ref. 68964). Apparently misidentified with closely related species in the northern and eastern Indian Ocean and western Pacific (however, Ref. 5978 seems to present a reliable record from western Indonesia).
西印度洋: 侷限於紅海與熱帶的西印度洋到南非了。 顯然地在印度洋北部與東部與西太平洋中被誤鑑成近親魚種了。 (然而, 參考文獻 5978 似乎呈現來自印尼西部的一個可靠的記錄)

簡短描述 型態特徵 | 形態測量圖

A large guitarfish with large black eyespots on the pectoral bases, a distinctive black cross between the eyes, and rows of small white spots on the upper body; snout pointed and lower caudal lobe short (Ref. 5578). Olive-green above, white below (Ref. 5578). Mouths small and contain flattened, pavement-like teeth.
一個大的犁頭鰩用大的黑色眼斑在胸鰭基底上, 在身體上半部上的眼 , 和列的白色小斑點之間的一個特殊的黑色十字; 吻尖而下尾部的葉短.(參考文獻 5578) 橄欖綠色的上方, 腹面白色的.(參考文獻 5578) 嘴小的而且包含平又平鋪的齒。

生物學特性     字彙 (例如 epibenthic)

Occurs inshore and in shallow estuaries (Ref. 5578). Feeds on crabs, lobsters, bivalves, small fishes (Ref. 5578) and squids (Ref. 37816). Ovoviviparous (Ref. 50449). Takes crayfish and pilchard bait. Meat and fins sought after in Asian markets (Ref. 30573).

生活於近海與在水淺的河口中.(參考文獻 5578) 吃螃蟹,龍蝦,二枚貝,小魚 (參考文獻 5578) 與烏賊。 (參考文獻 37816) 卵胎生的.(參考文獻 50449) 採取小龍蝦與沙丁魚誘餌。 肉口味極佳。 鰭在亞洲市場中追求。 (參考文獻 30573)

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

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). With 4 young, about 43-60 cm in length (Ref. 37816), born in the summer (Ref. 3919).西印度洋: 侷限於紅海與熱帶的西印度洋到南非了。 顯然地在印度洋北部與東部與西太平洋中被誤鑑成近親魚種了。 (然而, 參考文獻 5978 似乎呈現來自印尼西部的一個可靠的記錄)
