It's quite rare for invertebrates to eat seabirds (octopuses excepted--here's an octopus eating a seagull), but this observation shows that the giant anemones (Anthopleura xanthogrammica) will certainly go for some bird if the opportunity arises. Bad-ass, if you ask me. Guy and colleagues just published a study in _Marine Ornithology _describing the find, and two other occasions when anemones were seen eating seabirds. In one case, an anemone engulfed an entire seagull chick, leaving only its feet sticking out. GULP. In the other example, some cnidarians were seen ingesting a gull leg.
