The Dunkleosteus was an armoured fish with a length of eight to ten metres, which was unusually large for the Devonian period. It was one of the first giants of the underwater world, together with the Titanichthys.

Polar bears are the largest land-dwelling predatory animals on earth. Their thick, snow-white fur and thick layer of fat protects them from the cold.
