Researchers used a Remotely Operated Vehicle (ROV) to explore the depths of the East Scotia Ridge, which is full of hydrothermal vents which can reach up to 719 degrees Fahrenheit (382 degrees Celsius). They discovered an amazing new world packed with unknown species. According to project leader Professor Alex Rogers of Oxford University’s Department of Zoology, these alien-looking white creatures are thriving in the rich chemicals ejected by the vents (via Lost World Discovered Under Antarctica)

Finally, EEG-like recordings have been done in both octopus and cuttlefish, leading to the general (but very preliminary) finding that cephalopods have complex, low-frequency “background” electrical activity in some parts of their brains that seems to vary with their states of consciousness. In addition, they show sensory-evoked changes in this activity, in the same way that human EEGs do. This suggests that some of the gross functional properties of the cephalopod brain might resemble those of mammals on a system-wide level.

All of the arguments by analogy should be taken with a grain of salt, because while it is interesting to consider the possible theoretical importance of the apparent similarities between octopus and vertebrate brains, it seems premature at this point, given how little we know about them. While laterality, distributed low-amplitude electrical activity, and a certain kind of memory system architecture are found in the brains of animals who are almost definitely conscious (eg. mammals and birds,) it’s hard to say that their presence in such highly divergent nervous systems (eg. those of vertebrates and cephalopods) has the same set of functional consequences in all cases.

The two-year-old cephalopod has a record of predicting past German results in this manner, his owners say. Paul has so far correctly predicted all of Germany’s results in South Africa. His keepers say he correctly predicted nearly 70% of Germany’s results during the 2008 European Championship.

This octopussy is really invisible until it decides to show itself. Amazing.

Coconut-carrying octopus caught on camera - An octopus and its coconut-carrying antics have surprised scientists.

Underwater footage reveals that the creatures scoop up halved coconut shells before scampering away with them so they can later use them as shelters.

Writing in the journal Current Biology, the team says it is the first example of tool use in octopuses. Footage courtesy of Museum Victoria/Current Biology
