context_page_description: The oblong rocksnail is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Pleuroceridae.
  This species is endemic to the Cahaba River in Alabama, United States. It was thought to be extinct due to habitat loss since it had not been collected since 1933, and was formally declared extinct in 2000. The IUCN Red List listed it as extinct in 2006 and in 2012. It was rediscovered in a small section of its previously described habitat in the Cahaba River in 2011, with a formal report published in August 2012.
  Molecular systematic analyses are underway to clarify the genetic position of Leptoxis compacta.
context_section_description: Leptoxis compacta inhabits shoal upstreams.
  Reproductive behavior was observed on approximately 30 L. compacta individuals collected in 2011 and placed in captivity. Females laid eggs either singly or in short, single lines. Each egg was approximately 0.3 mm in diameter. Average length of the line of eggs was 1.57 eggs (n = 51 egg lines) with a maximum observed length of 3 eggs.
