Aussie Scientists Find Coconut-Carrying Octopus 205
An anonymous reader writes with this excerpt from an AP report: "Australian scientists have discovered an octopus in Indonesia that collects coconut shells for shelter — unusually sophisticated behavior that the researchers believe is the first evidence of tool use in an invertebrate animal. The scientists filmed the veined octopus, Amphioctopus marginatus, selecting halved coconut shells from the sea floor, emptying them out, carrying them under their bodies up to 65 feet (20 meters), and assembling two shells together to make a spherical hiding spot. ... 'I was gobsmacked,' said Finn, a research biologist at the museum who specializes in cephalopods. 'I mean, I've seen a lot of octopuses hiding in shells, but I've never seen one that grabs it up and jogs across the sea floor. I was trying hard not to laugh.'"

Funny thing is that split coconuts probably aren't too common unless people or animals split them.

They may have the first video evidence, but I'm sure I've heard about octopodes using tools before, and Google turns up one [radthoughts.com] reference almost three years ago about a very similar case, and a 2008 paper [berkeley.edu] (PDF) which reports observation of octopus tool use and references a 1984 paper as describing certain octopus behaviour as probably tool use. I'm not sure from the Google Scholar description of this 1999 paper [elsevier.com] whether it refers to mention of octopus tool use in 1940 or in Roman times:

No need. Pliny's Natural History was published at some point around AD 78. However, when you cite your sources as a scholar, you put the date of the edition you have in your hands. Hence, this person put "1940".
