This diamond-shaped ray is much wider than it is long, usually 3 to 4 feet wide, and its short tail lacks the ray’s usual spine. It can vary from light brown to grey to greenish, with lighter or darker spots, and can manipulate its shading to blend better into its background. It is tolerant of a variety of salt content, from brackish river mouths to highly saline lagoons, as long as there is a muddy or sandy bottom to hunt small fish and invertebrates.
