The strongest animal on land in terms of absolute strength is likely the African bush elephant, whose weight can range up to 13 tons (11.79 metric tons), and whose carrying capacity is at least 5 tons (4.53 metric tons). Despite this, African bush elephants are afraid of some tiny insects, like honey bees. When scared or upset, an African bush elephant can run at 25 mph (40 km/h), which gives an idea of its strength.

In general, the strongest animal is the blue whale, weighing above 209 tons (189.6 metric tons), with a length of 100 ft (30 m). It can travel up to 30 mph (50 km/h) in short bursts. The kinetic energy of a whale at such a speed probably outclasses any other animal by an order of magnitude.

Historically, some of the largest dinosaurs (like Brachiosaurus or Supersaurus) were stronger than any living animal. http://www.wisegeek.org/what-is-the-strongest-animal.htm#didyouknowout
