" Kali was extremely lucky to have lived as long as she did. Most octopuses die as paralarvae. Only two in 100,000 hatchlings survive to sexual maturity-otherwise the sea would be overrun with octopuses. "And at least we know she had a good last day, " I said. "Yes," said Wilson. "She had a day of freedom. And that she got out tells you a phenomenally inquisitive and intelligent creature wanted her freedom. We know, clearly, it must have taken a lot of effort to get out. A stupid animal wouldn't do that."

"She died like a great explorer," I said. Like the astronauts who died blasting off in Challenger, or the brave men who perished in attempts to find the source of the Nile, penetrate the Amazon, visit the poles, Kali had chosen to face unknown dangers in the quest to widen the horizons of her world.
