Resumen:
The karstic cave, la Cueva de Los Sabinos, located in the Sierra de El
Abra in the state of San Luis Potosi, Mexico, is mostly known for
hosting a population of blind, depigmented Astyanax mexicanus cavefish.
Herein, we report the discovery of a non-pigmented sponge (Porifera) in
the final sump of this cave. No genus or species name could be
attributed because we did not collect any specimen. Up to now, the
sponge distribution seems restricted to a single pool in la Cueva de Los
Sabinos, but further careful exploration of other pools of the cave as
well as closely related cavities is warranted. To our knowledge, this
observation constitutes the fourth report of a freshwater, white,
cave-adapted sponge in the world and the first for Mexico and North
America. It is also the eleventh troglobite species encountered in Los
Sabinos. Our discovery confirms the exceptionally rich biodiversity of
this cave ecosystem.
