Octopus

Maybe it's a bit dull to talk about ginkgo nowadays. The hottest creature on earth at this moment is no doubt Paul the Octopus.

Of course everything mentioned in the sensational literature is superstitious. Nonetheless, octopus has a superb intelligence - it is one of the only three animals (and the only invertebrate) that could use tools and solve problems. For example, seeing some food in a glass jar, an octopus could unscrew it and extract the content inside - without being shown how to previously.

The other two creatures that could do so are chimpanzee and university graduates (I hope).

PS. Although the eyes of the octopus, like that of vertebrates, have retina, cornea, iris, lens, and a fluid-filled interior, their evolution is entirely different. Unlike human, objects are directly projected onto the retina of octopus - not upside down.

These similarities of structure, despite different origins, are a classic example of convergence evolution.
