Arthritis and Toads

I know we had discussed this in class so I want to look it up. In an article in the New York Times, The cane toad has been conquering northern Australia, but now they are paying for it. They have been growing too big and hopping into new territories, because of this the toads are developing severe arthritis.
In 1930s the cane toads were brought to Australia in order to control the insect problem in the sugar cane fields. The toads did solve the insect problem, but also, are very toxic to the animals that try to eat them. This has allowed them to expand their territory. Researchers have also seen that the toads have evolved with larger bodies and longer legs and now are able to move faster. Furthermore, researchers found that some of the cane toads had fused vertebrae caused by bony growths with spinal abnormalities. With each hop, it puts more stress on their skeleton.
