}}Luria isabella, common names Isabel's cowry, Isabella cowry or fawn-coloured cowry, is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries.[1] DescriptionThe shells of these very common cowries reach on average {{convert|25|-|35|mm}} of length, with a minimum size of {{convert|8|mm}} and a maximum size of {{convert|54|mm}}. The basic color of these cylindrical-shaped shells is light beige or fawn or pale reddish-brown, the dorsum surface is crossed by thin discontinuous longitudinal markings and the extremities show orange-red terminal spots. The base is mainly white and the long and narrow aperture has several short teeth. In the living cowries the well developed mantle is black matt and almost velvety, with external short antennae. DistributionThis species lives in the Red Sea, along the East African coast, the Mascarene Basin and in the Indo-West Pacific Ocean (Malaysia, Indonesia, Australia, Melanesia, Philippines, Southern Japan, Taiwan) up to Hawaii. HabitatLiving cowries of this species can be encountered in a wide range of habitats, in shallow and in intertidal waters up to about {{convert|35|m}} of depth. During the day they usually stay under rocks and stones or in small holes or coral caves. At dawn or dusk they start feeding on sponges, algae or coral polyps. SubspeciesThere have been a great many subspecies named, but most names are very dubious. However the following are generally accepted as valid names:
