I love that their justification for this study is robots. I think science for the sake of learning is good and justification isn't always necessary. But it's so funny that we've moved beyond search and rescue as a justification for cool robots, to cool robots as a justification for studying octopi.

How octopuses squeeze through too small gaps Obligatory click-bait title comment... The article describes how octopuses get through holes in one of two ways, one for larger holes and one for smaller holes. Spoiler: An octopus cannot get through a gap that is too small.

An octopus is what results when water gains consciousness.
