|Ravenous shrimp added to Lake Ontario's list of unwanted guests|

A half-inch-long blood-red shrimp is raising concerns in Lake Ontario.
Like most non-native species in the Great Lakes, the red mysid is presumed to have arrived in the ballast of oceangoing ships.
Typically, the shrimp feast on phytoplankton and zooplankton, the foundation of the lake's food chain. Zooplankton are also what many young fish thrive on.
So far, scientists have found red mysid only off Nine Mile Point in eastern Lake Ontario, but they are likely more widespread. They're asking the public's help to catalog the extent of the invasion.
