Porcupine looking to board Wonder Lake shuttle-late June 2012. Red teeth? This from AK wildlife biologist: Brown enamel is significantly harder than dentine (white part). As teeth are ground down with use, the white part erodes faster than the brown, which maintains the chisel-like sharp edge to the teeth, an adaptation for extremely sharp front teeth.
Porcupine Forest in Denali is so named since too many porcupines wintered over & killied the trees by eating the tender underbark to survive.
