Spinetail Devil Ray
Mobula mobularAlso known as Devil Fish, Giant Devil Ray, Spinetail Mobula, Mediterranean Devil Ray
Giant devil rays glide through deep offshore waters using their massive, pointed pectoral fins like wings. These gentle giants are famous for their spectacular aerial leaps, launching themselves completely out of the water before landing with a loud slap. They use their horn-like cephalic fins to funnel plankton and small schooling fish into their wide, terminal mouths.
