The civil defense office in the western state of Jalisco said Wednesday the first American suffered bites to his legs, arm, abdomen and chest. The second, who went in the water to help, suffered a wound to his hand.

The office said both men were given first aid at the scene. It said both men were from Colorado, but did not specify a hometown for either.
