Marine mammal experts in Northern California have resumed an effort to rescue a young sea lion from a canal.

The Marine Mammal Center confirmed Wednesday that the sea lion has re-emerged from a drainage pipe in the small city of Vacaville.

It's unclear how the sea lion got into the canal.

The closest body of water is the Sacramento River, about 50 miles north.

But experts at the center believe the animal likely traveled up the river, took a wrong turn and followed a series of agricultural ditches and waterways to get to the canal on Tuesday.

Mammal center spokesman Giancarlo Rulli says the sea lion is believed to be a young male, is fat, looks healthy and seems to be enjoying his adventure.
