Butterfly Ray Identification Guide

Key identification features

• Extremely wide, diamond or kite-shaped disc that is noticeably wider than it is long, more so than in almost any other ray family
• Smooth skin with no thorns, giving a soft, flattened appearance
• Sandy grey, brown, or olive upperside, often with faint mottling, spots, or blotches that help it blend with the seafloor
• Very short, thin, whip-like tail, usually much shorter than the disc width
• Small or absent tail spine in many species

Common look-alikes

• Stingrays typically have a longer tail relative to disc size and a disc that is less extremely wide-than-long
• Eagle rays have a longer tail and a distinct, projecting head separate from the disc, unlike the butterfly ray's smoothly continuous outline
• Guitarfish have an elongated, shark-like tail and body rather than a broad flattened disc

Where you'll see one

Found in shallow coastal waters, bays, and estuaries over sandy or muddy bottoms in warm-temperate and tropical seas worldwide. Butterfly rays often bury themselves almost completely in soft sediment, leaving only their eyes exposed, and their unusually wide, thin disc combined with a stubby tail makes them one of the easiest ray families to recognize at a glance.
