Crabby!
Originally uploaded by urtica.

We were at this Sandwich, MA tide pool to see the invasive colonial tunicate Didemnum, which we certainly did. But there were at least three other invaders there too, including this Asian shore crab, Hemigrapsus sanguineus. As this article notes, the Asian shore crab has become the most common crab species on many parts of the New England coast, even beating out other invaders like the green crab, Carcinus maenas.
