       A Limerick about Great White Sharks

  

          A man went to the sea and caught a shark,

          Then he took it to the crazy shark park,

          He let it eat a goose,

          But he wanted a moose,

          So the man took it out of the park.

The coloration makes it difficult for prey to spot the shark because it breaks up the shark's outline when seen from the side. From above, the darker shade blends with the sea and from below it exposes a minimal silhouette against the sunlight.

Great white sharks, like many other sharks, have rows of serrated teeth behind the main ones, ready to replace any that break off. When the shark bites, it shakes its head side-to-side, helping the teeth saw off large chunks of flesh.
