Paragraph 2
 
 
						  
						  
The scientists say their 
 findings are important as they give an 
 into how octopuses amend their behaviour in 
 to different stimuli. Scientists describe this process as "behavioural plasticity". Biologist Graziano Fiorito suggested that the research could help us understand more about intelligence in 
. He said: "The brain of the octopus is 
 analogous in many of its 
 to that of mammals....For this reason [the DNA] represents a very interesting 
 to study to improve our knowledge of the 
 of intelligence." He says the brain 
 of octopuses may mean the creatures are more similar to mammals than invertebrates and other sea 
.
