Because many squid have brain nerve fibres that are hundreds of times thicker than those of humans, neuroscientists have long used them for research. These nerve fibres have led to so many breakthroughs in the study of neurons that many scientists joke that the squid should receive a Nobel Prize.
The amazing thing about the sea is that it is perhaps the last truly unexplored frontier; most oceanographers estimate that only about ninety-five per cent of the sea has been studied. Meanwhile, the oceans are believed to contain more animals than exist on land, a majority of which have never been discovered.
