Aetobatidae (Pacific eagle rays)
Etymology: Aetobatus: Greek, aetos = eagle + Greek, batis, batidos = a ray (Raja sp.) (Ref. 45335).
Eponymy: Narinari was a word used in Brazil in the 17th and 18th centuries and means ‘stingray’. [...] (Ref. 128868), visit book page.
Taxonomic Remarks
Status of Aetobatus latirostris Duméril, 1861 requires further investigation. Species information (common names) should be linked to correct species (see Ref. 114963).

Commonly found in coastal habitats to at least 60 m depth (Ref. 114953). Swims close to the surface, occasionally leaping out of the water, or close to the bottom (Ref. 3175). Frequently forming large schools during the non-breeding season (Ref. 7251). Feeds on polychaetes, bivalves, gastropods, cepahlopods, shrimps and small fishes (Ref. 114953). Ovoviviparous (Ref. 50449). Bears young in litters of 2-4 (Ref. 26938, 114953).

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). Bears up to 4 young (Ref. 5578, 6871, 37816). Width at birth 17-35 cm (Ref. 37816).
According to Uchida et al (1990) (Ref. 51119) 'the male chases the female in mid water, then nibbles on her dorsal surface. The female stops swimming to begin copulation. The male bites the female on a pectoral fin and bends one clasper forward, then attempts an abdomen to abdomen copulation with either clasper, usually mid-water' (Ref. 49562). Copulation lasted for 20 seconds to 1 minute (Ref. 49562).西大西洋: 北卡羅萊那州 (夏天) 與美國的佛羅里達與百慕達群島到巴西南部。 在墨西哥灣與加勒比海各處, 包括安地列斯群島.(參考文獻 26938) 東大西洋: 茅利塔尼亞到安哥拉.(參考文獻 4440) 印度-西太平洋: 紅海與南非至夏威夷,北至日本, 南至澳洲.(參考文獻 9862) 東太平洋: 加州灣到祕魯的波多立哥皮薩羅與加拉巴哥群島.(參考文獻 5530) 在那裡可能是有斑點 Aetobatus 的超過一個種。 (參考文獻 9862)
