Four red river hog piglets were recently born and introduced to the public at the San Diego Zoo Safari Park.

The zoo said the first piglet was up and running around before the last one was delivered.

When grown, they will have a raised white mane down their spine, black and white tassels on the tips of their ears, and dark rings around their eyes.

Those markings help make them look larger to their natural predators.
