The spotted eagle ray, hīhīmanu in Hawaiian, is one of the most beautiful and graceful animals in the sea. Its dark dorsal surface is decorated with hundreds of white spots — a pattern as unique to each individual as a human fingerprint. With wing-like pectoral fins spanning up to ten feet, it glides through the water with slow, powerful beats.

Eagle rays feed primarily on hard-shelled mollusks and crustaceans, which they crush with flat, plate-like teeth. They use their duck-bill-shaped snout to root through sandy bottoms, sometimes creating large excavation pits that other fish then exploit for exposed prey.

Hīhīmanu are known for their spectacular leaping behavior — launching completely out of the water and belly-flopping back in. Scientists think this may help dislodge parasites, communicate with other rays, or simply be a form of play.

In Hawaiian culture, the eagle ray was admired for its beauty and grace. The word hīhīmanu combines hīhī (rays of the sun) and manu (bird), reflecting how Hawaiians saw the ray as a creature that flew through the sea the way birds fly through the sky.
