Cerion nanus | |
Cerion nanus is a species of medium-sized air-breathing land snail, a terrestrial pulmonate gastropod in the family Cerionidae.
This species is endemic to the island of Big Cayman, Cayman Islands in the Caribbean Sea, [3] where it is found among Evolvulus arbuscula and E. squamosum plants, [4] which grow in this coastal dry limestone shrub. Shells were found in 1975 at three sites, encompassing a total area of 35,000 m2 surrounding the North Shore Track. It is sympatric throughout its range with Cerion pannosum, a species with a much larger distribution and shell-size, which has probably ecologically replaced C. nanus. However, this replacement has not yet occurred, suggesting that this species may have never had a larger population. Currently several small populations exist along the Spot Bay Road in numbers far larger than originally suspected. [5] C. nanus can be identified by the color of their shells, which are grayish or white, and emerge from their hibernation during rainy days but are difficult to identify during dry weather. [6]
The Laysan rail or Laysan crake was a flightless bird endemic to the Northwest Hawaiian Island of Laysan. This small island was and still is an important seabird colony, and sustained a number of endemic species, including the rail. It became extinct due to habitat loss by domestic rabbits, and ultimately World War II.

In 2007, the species was rediscovered after being considered to be extinct.
