Potamides obtusus (Lamarck, 1822) Cerithidea obtusa is a species of sea snail, a marine gastropod mollusk in the family Potamididae.

[1] The Obtuse Horn Shell, also known as Mud Creeper, is a relatively common snail found in muddy coastal areas.

It is used as a food in Southeast Asia, where it is known by the name of Belitung and Siput Sedut in Malay, Hoi Joob Jaeng (Thai: หอยจุ๊บแจง), and Ốc Len in Vietnamese.

Many South East Asians eat the mud creeper as a dish, particularly in Malaysia, southern Thailand, certain parts of Indonesia, and Vietnam.
