板鳃亚纲 (鲨鱼与 鱼) (sharks and rays) >

生态学
海洋 居于水底的; 深度上下限 0 - 60 m (Ref. 106604). 亚热带的; 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: 泰国湾与菲律宾到澳洲的昆士兰省。 一个相似种与也许同一种出现于西印度洋莫桑比克外海中与在亚丁湾而且可能与西印度洋与红海的真实 ' Rhynchobatus djiddensis' 重迭分布。 分布区域可能比纪录宽, 但是 Rhynchobatus djiddensis 从西太平洋的许多分类命名纪录与东南印度洋不能够被鉴定到种。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm ?, range 155 - ? cm
Max length : 124 cm TL 雄鱼/尚未辨别雌雄; (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).
在大陆架上栖息于近岸水域。 (参考文献 9915) 吃底部甲壳动物与软件动物。 (参考文献 9915) 卵胎生的.(参考文献 50449) 也捕获网。 (参考文献 9915) 在市场上销售生鲜地了; 鳍因为鱼翅贸易而被重视了。 (参考文献 9915) 母标本可能在泰国达到 300 公分长。 (参考文献 9915)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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: 泰国湾与菲律宾到澳洲的昆士兰省。 一个相似种与也许同一种出现于西印度洋莫桑比克外海中与在亚丁湾而且可能与西印度洋与红海的真实 ' Rhynchobatus djiddensis' 重迭分布。 分布区域可能比纪录宽, 但是 Rhynchobatus djiddensis 从西太平洋的许多分类命名纪录与东南印度洋不能够被鉴定到种。
