Ocellate river stingray
蜇伤The ocellate river stingray is a freshwater stingray with a round, flat body and yellow-orange spots on its back. It lives in rivers across much of tropical and subtropical South America. It is the most widespread member of its family, and it is sometimes kept in aquaria.1

怎样认出它
- Its disc is roughly circular in shape.1
- Its eyes are raised from the upper surface of the disc.1
- The back is typically beige or brown, with numerous yellow-orange spots that have dark rings.1
- The exact colour and pattern of spots vary between individuals and between locations.1
常被误认为: Several closely related species were once grouped with it, including P. amandae, P. pantanensis and P. marquesi. The "mantilla ray" (now named P. marquesi) lacks the black-edged yellow-orange spots.1

它对人有多危险?
对人的危险: 严重被蜇了要去看医生。死亡非常罕见。
如果它蜇人
- 把伤口泡在热水里,水温以不烫伤为限、尽量热(先用你自己的手试一试),泡 30 到 90 分钟。去看医生,尤其是被石头鱼和魟鱼伤到时。
一定先拨打你的急救电话(112、000、911)。这里是一般急救指导,不是医疗建议。 急救基础
注意安全
- 永远不要摸、抓或逗弄野生动物,即使是很小的,即使它看起来在睡觉或已经死了。
- 给它留出空间。如果遇到它,保持冷静,慢慢后退,让它走自己的路。
- 如果被它蜇了:保持冷静,保持不动,拨打你的急救电话(112、000、911)或尽快去医院。记住它长什么样,拍张照片会有帮助。
它不是冲着你来的。它用毒液捕猎或保护自己,而且它更愿意躲起来。 更多安全知识

The largest recorded weight is 34.2 kg, but the official IGFA record is 12.59 kg.1
It is one of the most popular freshwater stingrays kept in aquaria, and it breeds readily in captivity.1
Populations vary so much in appearance that scientists have grouped several similar species together as a species complex.1
