Procaris noelensis

Procaris noelensis is a species of shrimp, a single specimen having been described by Bruce & Davie from a freshwater/tidally influenced cave system on Christmas Island in 2006.

[2] This species is widely separated geographically from other members of its genus and may be a relict species from the Mesozoic fauna of the Tethys Ocean, with Christmas Island being its refugium.

[3] This theory is reinforced by the fact that it was found living in sympatry with a hippolytid shrimp and an atyid shrimp, the latter coming from another ancient lineage and often found inhabiting anchialine systems.

[2] Procaris is a small genus of aberrant shrimps with only five known members.

This species is known from a single female individual, the holotype, found in an anchialine cave where saltwater intrudes into the karst limestone.
