There's a lot of activity In the nursery of Arizona's Wildlife World Zoo. Among the bevy of beastly babies is a quartet of very young Warthog piglets. Photographed earlier this month by Arizona reader Nicki Miller, the hoglets look harmless now (and likely will remain that way!) but they will grows tusks of up to 9 inches long. Their wild cousins use these chompers for digging, for combat with other hogs, and in defence against
predators.
