About the Sunfish

From all animals, the sunfish grows most during its lifetime. It hatches from a tiny egg and grows to 1,200 pounds and 10 feet long, an increase in size of about 60 million times. For us the sunfish is nature's best symbol for exponential growth. (Source: National Wildlife Federation)
