- A human participant in a fishing derby in the Tacoma Narrows posed for a photo contest with a captured octopus on her face. The octopus bit her in self-defense. The human eventually went to the emergency room. "And I'm still in pain," she said. "I'm on three different antibiotics. This can come and go, the swelling, for months they say." She says the whole painful experience taught her a valuable lesson about handling live octopuses, which have powerful beaks and poisonous venom. No word on the condition of the octopus.

The southern sand octopus (Octopus kaurna) lives in sand flats around southern Australia and Tasmania. Unlike most octopuses, the sand octopus cannot change its color. Instead it uses its siphon to blast sand beneath it, suspending the sand in water, making its own quicksand that it can pull itself down into for shelter.
