簡短描述 型態特徵 | 形態測量圖

Front of head semicircular in outline. No other hammerhead has front of head in semicircle. (Ref. 26938).
頭部前端半圓的輪廓。 沒有其他的 hammerhead 在半圓形中有頭部前端。 (參考文獻 26938).

生物學特性     字彙 (例如 epibenthic)

Found on the continental and insular shelves, on inshore and coastal areas, over mud and sand bottoms, also on coral reefs. Often occur in shallow water including estuaries, shallow bays and over coral reefs (Ref. 9987). Spends night time hours on shallow grass flats, searching for nocturnally active invertebrate prey, moves into deeper water during the day (Ref. 27549). Feed mainly on crustaceans, also on bivalves, octopi, and small fish. Viviparous, with 6 to 9 young per litter. Size at birth about 35 to 40 cm. Not territorial. Always occurs in small groups. Considerable sexual segregation occurs. Shows diel rhythm of activity. Utilized for human consumption and processed for fishmeal.

在沿海地區與沿岸區域上,棲息於大陸棚與島嶼棚了, 在泥與沙底部之上, 也在珊瑚礁上。 時常出現於淺水區包括河口,淺灣中與在珊瑚礁之上.(參考文獻 9987) 主要吃甲殼動物, 也在二枚貝,章魚與小魚上。 胎生的,6 到 9個幼魚每胎。 出生時的大小大約 35 到 40 公分。 不是具有領域性。 總是形成小群魚群。 相當多的性別異形性出現。 顯示活動的日週期性節律。 供人類食用而且加工成魚粉。
