High Quality Content by WIKIPEDIA articles! The snake river physa snail is a species of gastropod in the Physidae family endemic to Idaho in the United States. The Snake River physa snail Haitia natricina Taylor, 1988 is a freshwater mollusc found in the middle Snake River of southern Idaho. It has an ovoid shell that is amber to brown in color, and has 3 to 3.5 whorls. The physa can reach a maximum length of about 6.5 mm. The Snake River physa is believed to have evolved in the Pleistocene-Holocene lakes and rivers of northern Utah and southeastern Idaho. The species may have existed in the Snake River for approximately 3.5 million years ago. While much information exists on the family Physidae, very little is known about the biology or ecology of this species. It is believed to be confined to the Snake River, inhabiting areas of swift current on the undersides of large cobbles and boulder-sized rocks.
