("belonging to the genus Manta. The larger species, M birostris, reaches 7 m in width while the smaller, M alfredi, reaches 5.5 m"/ The name "manta" is Portuguese and Spanish [a noun feminine in both language] for mantle (cloak or blanket), a type of blanket-shaped trap traditionally used to catch rays)

(b) Contrary to the title (but not the body) of the Chinese translation, a manta ray is NOT poisonous. A stingray is. See stingray https://en.wikipedia.org/wiki/Stingray
(certain "stingray's defensive reflex (use of its poisoned stinger) may result in serious injury or death")
View photos in teh Wiki page to see the (sole) stinger on the tail.
