Beware of the Coastal Invaders!

Caption: picture taken by Christian Fischer at the Havel River in Germany, October 2007.

Yikes! "Aliens" are invading coastlines around the world! One species has dark, hairy claws. Another invader might glow an eerie green color if it is disturbed during the night. What are these strange creatures, and where do they come from?

Fortunately, these "aliens" are not from outer space. The creature with hairy claws is a brown Chinese mitten crab. The eerie, glowing invader is a comb jellyfish. Why are these creatures called invaders? They are showing up on coastlines far from their native habitats. Their presence is causing many problems in their new homes.
