板鰓亞綱 (鯊魚與魟魚) (sharks and rays) >

生態學
海洋 居於水底的; 深度上下限 0 - 60 m (Ref. 106604). 亞熱帶的; 30°N - 30°S, 30°E - 155°E (Ref. 114953)
Indo-West Pacific: Red Sea, Persian Gulf (Ref. 114953). Gulf of Thailand and the Philippines to Queensland, Australia. A similar and perhaps identical species occurs in the western Indian Ocean off Mozambique and in the Gulf of Aden and is probably sympatric with the true 'Rhynchobatus djiddensis' of the western Indian Ocean and the Red Sea. Distributional range probably wider than reported, but many nominal records of Rhynchobatus djiddensis from the western Pacific and southeastern Indian Ocean cannot be identified to species.
西太平洋: 泰國灣與菲律賓到澳洲的昆士蘭省。 一個相似種與也許同一種出現於西印度洋莫三比克外海中與在亞丁灣而且可能與西印度洋與紅海的真實 ' Rhynchobatus djiddensis' 重疊分佈。 分佈區域可能比紀錄寬, 但是 Rhynchobatus djiddensis 從西太平洋的許多分類命名紀錄與東南印度洋不能夠被鑑定到種。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 155 - ? cm
Max length : 124 cm TL 雄魚/尚未辨別雌雄; (Ref. 114953); 300.0 cm TL (female)
Inhabits inshore waters on the continental shelves (Ref. 9915). Demersal on soft bottoms and near coral reefs (Ref.58048). Female specimens may reach 300 cm in length in Thailand (Ref. 9915). Feeds on bottom crustaceans, mollusks (Ref. 9915) and bottom-dwelling fishes (Ref. 114953). Ovoviviparous (Ref. 50449). Caught commonly by demersal tangle net, and to a lesser extent by trawl and longline fisheries (Ref.58048). Marketed fresh; fins prized for the sharkfin trade (Ref. 9915).
在大陸棚上棲息於近岸水域。 (參考文獻 9915) 吃底部甲殼動物與軟體動物。 (參考文獻 9915) 卵胎生的.(參考文獻 50449) 也捕獲網。 (參考文獻 9915) 在市場上銷售生鮮地了; 鰭因為魚翅貿易而被重視了。 (參考文獻 9915) 母標本可能在泰國達到 300 公分長。 (參考文獻 9915)
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 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).西太平洋: 泰國灣與菲律賓到澳洲的昆士蘭省。 一個相似種與也許同一種出現於西印度洋莫三比克外海中與在亞丁灣而且可能與西印度洋與紅海的真實 ' Rhynchobatus djiddensis' 重疊分佈。 分佈區域可能比紀錄寬, 但是 Rhynchobatus djiddensis 從西太平洋的許多分類命名紀錄與東南印度洋不能夠被鑑定到種。
