The Gray Whale
The gray whale, which is often seen with barnacles encrusted across its skin, can live up to 80 years. They can weigh up to 90,000 pounds and grow to be 49 feet long if they live that long. When compared to the passengers on the boat, one is clearly larger than the other.

These tropic-dwelling creatures, also known as flying foxes or fruit bats, are nearly the size of men but eat fruits, plants, and insects. Surprisingly, these bats depend heavily on vision rather than echolocation.
