Sea pickle invasion

The waters off the Oregon coast are mysteriously awash with strange, jelly-like creatures that look like translucent slugs, according to the National Oceanic and Atmospheric Administration (NOAA).

Each pickle-like creature is, in fact, a colony made up of individual zooids that join to create a hollow, tube-like structure that has one closed end and one open end. (A zooid is a small, multicellular organism that makes up part of a colonial animal, and can arise from another zooid by budding or dividing.)
