2 Invasive Species Found in S.C. Waters

CHARLESTON, S.C. - Two new invasive species have recently been found along the South Carolina coast - a massive barnacle that dwarfs those found in the state as well as the Asian green mussel, which reproduces quickly and can pose a threat to floating docks.
The barnacle is native to the Pacific coast from southern California to South America. It is so big, colonies have been known to sink navigational buoys, slow boats and clog coastal water pipes.
The barnacle, the megabalanus coccopoma, was found by a College of Charleston student doing research this fall on the Folly River. It reproduces quickly, and, although only one has been found, scientists worry it could spread.
"There's not a whole lot known about this guy," said David Knott, an biologist with the state Department of Natural Resources who deals with marine invasive species. "Cold water may be a barrier to it."
"This guy could cause a lot of problems just due to size alone," said Sam Crickenberger, a senior marine biology major at the college who found the barnacle. "And it's sharp."
The Asian green mussel was found in the Charleston area earlier this year. It also reproduces quickly and can sink floating docks.
"Man, it's going to be crazy," said Larry Smith of Larry's Diving, who cleans hulls. People who don't keep up boat maintenance "aren't going to be able to move."
The new creatures are among the latest invasive species found in the state. The invaders can be brought from other parts of the world in the ballast of steamships or can drift in on plumes of warm water.
Scientists have identified nearly 40 invasive coastal aquatic invertebrate species in the state.
While the state appears to be at the northern end of the range for many tropical marine species, rising water and air temperatures could extend that range farther north.
Knott said there may be no stopping invasive species, but that slowing the spread is critical to preserving the state's coastal environment.
"If you look at the rate of introduced species, it's an exponential curve. That's a cause of concern."
