Hi Anania, I enjoyed reading about your information on the octopus. It seems pretty amazing that each arm has its own brain. I wonder how they manage to coordinate them so they all do the right thing at the right time? Fortunately the octopuses we have in New Zealand are pretty harmless, but the most poisonous ones are the tiny blue-ringed octopus found in Australia.
I also liked you slides about de-extinction of the mammoth. I wonder if scientists will end up doing this. One thing that helps them is that mammoth DNA has been preserved frozen in the Siberian permafrost, so the DNA is still good enough to figure out how it all fitted together. For a lot of extinct species we don't have such good DNA left over in their fossils. Kepp up the good learning.
