The North American bullfrog is a voracious carnivore with a seemingly insatiable appetite. It devours virtually anything in its path. In times of need, it will even eat its own kind. These frogs were introduced to the western United States in the early 1900s. Today, with few natural enemies, they are devastating the local ecosystem. Thus began the hunt for the bullfrog.
It's one of the ocean's most extraordinary and mysterious creatures. It's often seen, but very little is known about it: it's the bluefin tuna. It's faster than a dolphin and its hunting prowess rivals that of a great white shark. Traveling at over fifty miles per hour, it crosses the oceans. However, very little is known about its movements and life history; it's a creature so evolved that it escapes human observation. National Geographic guides us on a journey to discover the bluefin tuna.
