Strong

"Strong" - Illustration Friday challenge for September 4.
The strongest animal on land in terms of absolute strength is likely the African Bush Elephant, whose weight can range up to 13 tons, and whose carrying capacity is at least 5 tons.
The strongest animal in general is the Blue Whale, weighing above 209 tons, with a length of 30 m (100 ft). It can travel up to 50 km/h (30 mph) in short bursts. The kinetic energy of a whale at such a speed probably outclasses any other animal by an order of magnitude.(source: wisegeek.com)

This is an older piece...but I found it was perfect for the theme!
