James from Seattle/Olympia writes in with a discovery he made in his Christmas tree:

2008-12-25: "Pacific NW Xmas tree Octopus"

Just letting you know, we spotted this adventurous tree octopi feeling particularly festive.

Sometimes tree octopuses hitch a ride in Christmas trees harvested from farms on the Olympic Peninsula. When its tree is being jostled violently, a tree octopus will hunker down deep inside the branches near the trunk and camouflage itself to look like bark. This is a defensive mechanism to protect it from wind storms and sasquatch trying to shake octopuses to the ground. They may stay hidden like this for days after a particularly violent shaking, such as experienced by Christmas trees when they are chopped down and transported.

Many octopuses have a natural instinct to decorate their lairs with attractive baubles, and O. paxarbolis is no exception. When it finally comes out of hiding and explores its tree, finding it covered in shiny ornaments and sparkly lights, it will become so mesmerized by the baublely abundance that it'll hardly notice that its tree is sitting in some human's living room.

Scandinavian immigrants considered it good luck to find a tree octopus in their Christmas tree. Granted, that's because they like to eat them. But for us more enlightened cephalopodophiles, we can consider it a sign of good luck that the species hasn't yet gone extinct.

And to keep it that way, please remember to remove any octopuses you find before disposing of your Christmas tree. They can be put in a shoe box -- with a bit of moist branch to make them feel comfortable and some tinsel to keep them distracted -- and taken to your nearest chapter of the Friends of the Pacific Northwest Tree Octopus for reintroduction into the wild.
