Big Damage From Little Squirts

Invasive sea squirts establish themselves in tidal areas, crowd out native species in their path, and pose a threat to protected species of eelgrass. WHOI biologist Mary Carman (at right) explains the damage being done in New England coastal waters to a group of science writers during the 2010 Ocean Science Journalism Fellowship.  The program, established in 2000, introduces science journalists to the interdisciplinary and wide-ranging fields of oceanography and ocean engineering.(Photo by Tom Kleindinst, Woods Hole Oceanographic Institution)
