How do blind cavefish survive their low-oxygen environment? Remarkable fish have a hidden evolutionary adaptation — big red blood cells
Cavefish have obvious adaptations such as missing eyes and pale colors that demonstrate how they evolved over millennia in a dark, subterranean world. Now researchers at the University of Cincinnati say these incredible fish have an equally remarkable physiology that helps them cope with a low-oxygen environment that would kill other species. Biologists in UC’s […]
