Octopuses are perhaps the most complicated group of species on the planet. They have an evolutionary history that goes back over 500 million years, a period long before plants even moved onto land. Their genome shows an unprecedented level of complexity with a staggering 33,000 protein-coding genes identified (that's more than in a human being!). Octopuses possess highly developed brains and are considered as the most intelligent invertebrate demonstrating elaborate problem-solving behaviours. T
