Excorallana tricornis is a common corallanid isopod found in Florida, the Caribbean and the

in Syringodium and Thalassia seagrass beds, and in deeper
waters on brown alga Turbinaria, on Madracis sp. sponge,
on Agaricia sp. coral, on the gills of rays Aetobatus narinari and Dasyatis, and on squirrel fish. A closely related subspecies, E. tricornis occidentalis, is found on the Pacific coast from Mexico
