Marshall, Texas ? A truck transporting zoo animals overturned Tuesday, spilling 24 penguins, an octopus and tropical fish along a highway near Marshall, authorities said.

“We had a penguin wreck,” said Department of Public Safety Trooper Richard Buchanan. “They were thrown out into a ditch and in the roadway.”

Three penguins that landed in the highway were killed by oncoming traffic and one died in the crash, authorities said. Another penguin suffered a broken wing.

The driver, Kelly Hodge, 34, and passenger Tammy Root both sustained minor scratches and bruises, police said. Root was taken to a local hospital for treatment and released, authorities said.

Most of the fish lived and the octopus appeared unharmed, officials said. The octopus and fish were traveling in plastic bags, and some fish died when the bags burst, Buchanan said.
