"Octopuses are probably the most intelligent creatures outside of the vertebrate phylum to which we humans belong (which includes fish, amphibians, reptiles, birds and mammals). It's a fact that the octopus has a very good capacity for learning and has been shown to develop skills during tests. Their curiosity is amazing&amp;#8230; you really feel they &amp;#8220;scan&amp;#8221; you when looking at them face to face . It has been estimated that they are as smart or even smarter than dogs."^^<http://www.w3.org/2001/XMLSchema#string>
