One picture even shows how he came face-to-face with one of the sword-nosed hunters as sardines took cover behind him during one raid. Every year the sardines migrate along the Yucatan coast attracting predators like sailfish.
As they are attacked from all sides the sardines form defensive bait balls. By grouping together, they look for safety in numbers hoping to thwart the animals trying to pick them off.
And taking even more desperate measures, the sardines even used Reinhard for protection.
