Aliens species invading the Galapagos?

While it might be a bit too early to worry, the BBC reports on a sudden influx of non-native and potentially threatening species on the Galapagos Islands:

"Officials in Ecuador say they are worried about the discovery of foreign species on the Galapagos Islands. Despite inspections of incoming ships and planes, local people recently found an iguana and a turtle which probably came from mainland South America. "

Keep those iguanas at home, folks.
