Cozumel fox (Urocyon sp.) The still unnamed species whose is apparently close to extinction or even already extinct, is or (was until recently) found on the island of Cozumel, Mexico (Cuarón et al., 2004). The Cozumel Fox, which has not been scientifically described to date, is a dwarf form like the Island Fox but a bit larger, being up to three-quarters the size of the Grey fox (Gompper et al., 2006). The conservation status of a species is an indicator of the likelihood of that species continuing to survive. ...
