Biological Notes

Perez et al. (2020) found the following: "Histological analysis showed that the vestigial eyes of Phreatobius cisternarum contain a rudimentary lens. Transcriptome analysis revealed a repertoire of eleven visual and non-visual opsins and the expression of 36 genes involved in lens development and maintenance. In contrast to other cavefish species, such as Astyanax mexicanus, Phreatichthys andruzzii, Sinocyclocheilus anophthalmus and Sinocyclocheilus microphthalmus, neuromast staining patterns did not show an increase in the number of sensory hair cells" (from their Abstract). Further important results on this very significant subterranean fish, which has hardly been studied, are expected from this research group.
