JERUSALEM—In most zoos, a peccary would warrant scant attention. The grunting, short-legged New World critter doesn't spout water like crowd-pleasing elephants or pick visitors' pockets like mischievous lemurs. What it does boast, though, is a passing resemblance to a pig. In super-religious Jerusalem, this is enough to reel in crowds of curious conservative Haredi Jews and Palestinian Muslims.
