Dimensions of the chelae and the pleon are used to determine the average size at the onset of morphometric maturity in Aegla (Colpo et al. 2005; Viau et al. 2006; Bueno and Shimizu 2009).

The evolutionary path of populations of land-locked marine aeglids would favour the acquisition of physiological adaptations and changes to life history strategies that helped them cope with increasing exposure to less saline waters. The successful adaptation to freshwater habitats marks the origin of the taxon Aegla and the beginning of its dispersal and speciation history throughout southern regions of South America from the Paciﬁc to the Atlantic. The uplifting of the Andes Cordillera represented an important physical barrier leading to the separation of Aegla populations on the western side of the Cordillera (mostly found in Chile today) from those on the eastern side.
