Melongena patula, common name Pacific crown conch, is a species of large sea snail, a marine gastropod mollusk in the family Melongenidae.
Melongena patula has a shell that reaches a length of 75 – 250 mm. The surface of this shell shows a deep chestnut brown color lined with a few white or yellow spiral bands. The interior is white. The shell is quite slender, sometimes spiny on the shoulders, with a wide aperture.
This species can be found from the Gulf of California (Mexico) to Peru.[1]
These sea snails live in shallow water, usually in sandy or muddy areas, especially under mangrove trees.
