Why are dogs able to sniff out diseases? Study reveals reason

The animal world is dominated by the most colourful colours and the strangest and most interesting shapes. However, there are also specimens that can change their physical conformation so much that they are practically unrecognisable. 

These transformations can be instantaneous or can take weeks or even several years to complete. All, however, have a purpose. Some serve to defend themselves from predators, or to better adapt to their surroundings, or even to attract a partner to mate. 

The wonders of nature are yet to be discovered in their entirety, but in the meantime, take a good look at how some animals are able to... change themselves.
