For endangered species, it pays to be a large mammal with sad eyes that cuddles its babies. Glamorous animals, big predators and, above all, the extremely cute and fuzzy stand a chance of getting people to protect them and their habitats. Ugly animals - as judged by human eyes - are far more likely to be left aside when humans draw up conservation plans. Anyone care to save Ontario's rattlesnakes? Canadian ecology experts say such thinking means we're in danger of re-shaping nature to beautify it according to human notions of what's pretty, saving the mammals but letting the reptiles and amphibians disappear.
