Anchialine Shrimp
Procaris sp.
Sighting evidence at El Tanque, Bay of Pigs
Ghostly pale shrimps inhabit the deepest sections of the cenote where light barely penetrates and salinity matches full marine conditions. They have reduced pigmentation and enlarged antennae adapted for navigating the anchialine darkness, feeding on organic particles that settle from the water column above. Their presence confirms active underground connections to the sea and flags El Tanque as a scientifically significant anchialine habitat.
