Shark Week (Day 4)

Shark Week continues, and so does my coverage of bizarre-but-true shark facts.

SHARK FACT: Tiger shark livers are saturated in oil.  This allows for more buoyancy, so sharks can balance in the water better.  This explains the sudden spike in pelicans and dolphins in the Gulf who can not only balance better, but cannot physically submerge themselves in water whatsoever.  This is totally acceptable though, because most dolphins are hydrophobic anyways.

Sharks are also excellent trash collectors, as they eat almost anything, from license plates to car tires.  Garbage collection companies all over the country are currently researching into the possibility of replacing all sanitation workers with sharks, to reduce the amount of landfill space.  Unfortunately, the road tests were less-than-helpful.
