Good to Know: A case report in a recent issue of the journal Emergency Medicine Australasia described the successful removal of a leech from an eyeball. A 66-year-old woman, gardening in her back yard in Sydney, had accidentally flicked some soil into her eye. By the time a surgeon could extract the leech, it had roughly tripled its body size by feeding on the eyeball's blood vessels. (The key, by the way: a few drops of saline solution).
In a recent journal article, researchers from the University of Whitwatersrand (South Africa) and the University of Sydney (Australia) reported that young male Augrabies lizards avoid older predatory males by, basically, cross-dressing (pretending to be female by suppressing their extravagant male coloration until they are fully developed and able to defend themselves). Thus, they avoid being attacked and, at the same time, increase their own freedom to hit on females. (They must still be careful, say the researchers, because the older males might whiff their male scent, which cannot be suppressed.)
