Ereerelus

Ereerelus is a genus of small, terrestrial gastropod mollusks in the family Achatinellidae. These snails are native to the Hawaiian Islands and are characterized by their relatively small, ovate shells. The genus was first described by William Healey Dall in 1870.

Members of the genus Ereerelus are typically found in moist, forested habitats, often on vegetation or among leaf litter. Their diet consists primarily of decaying plant matter and fungi. Reproduction in Ereerelus, as in other Achatinellidae, is believed to be ovoviviparous, with eggs developing within the female's body before live young are born.

The conservation status of Ereerelus species varies, with some facing significant threats due to habitat loss, introduced predators, and diseases. Several species are considered endangered or critically endangered. Research into their ecology and conservation is ongoing, with efforts focused on habitat preservation and captive breeding programs for some of the most vulnerable populations. The exact number of species within the genus can vary depending on taxonomic classifications.
