Combined with the recent discovery that lobsters are growing bigger as a result of climate change, this has me afraid for when the sea creatures finally come out of the water to attack us: “Octopuses have been observed carrying coconut shells in what researchers claim is the first recorded example of tool use in invertebrates.”
Update: According to reader, and Environmental Science Professor at University of Lethbridge in Alberta, Dan Johnson, “Ants, hermit crabs, caddisflies, and wasps use tools. I really hope they were misquoted. This makes no sense. The use of tools by other invertebrates has been well documented.” Here are some references.
