CHAPTER MYSTERY

A slime on thumb nail.

SLIME DAY AT THE BEACH

It was a warm October day in Massachusetts when phone calls started streaming in to beach offices, aquariums, and even 9-1-1 lines. Beaches near Boston were coated with a thick, glistening layer of jellylike ooze. Beachgoers were mystified and worried. Some thought there had been an oil spill, but police and fire personnel verified that it was not oil.

More slimy masses kept washing up onto the seashores. People noticed that some of the gooey blobs appeared to be pulsating with life. When they looked closely, investigators saw that the slime was made up of small, individual critters—each transparent and the size of a fingernail. But what were they? As you read this chapter, look for clues to help you determine what the slime was.

Never Stop Exploring Your World.

Discovering what the slime was is only the beginning. Take a video field trip with the ecogeeks of Untamed Science to see where the mystery leads.
