Subterranean aquatic Oligochaeta [PDF]

Freshwater Biology, 2009
Summary1. Aquatic oligochaetes appear to be pre‐adapted to live in the subterranean environment. However, in the absence of genuine troglomorphic characters, the stygobiotic status of groundwater oligochaetes can currently be inferred only from their exclusive presence in the subterranean environment.2.
