Lobatus costatus reaches 28 cm. Large gastropod with a thick beige-to-white shell, low spires with blunted spines, very thick flared lip (hence milk conch) edged in pink to orange. Flesh eaten across the Caribbean. Moves slowly over sandy bottoms and seagrass between 1 and 30 m by characteristic leaps on its hooked foot. Cousin of Strombus gigas (Aliger gigas, in seed) but smaller and stockier.
