The Channeled Applesnail has invaded!

Picture of the Moment

With a 150-600mm zoom lens I can go into the lake without going into the lake, so this morning I went into Lake Murray to get some pictures of the Channeled Applesnail (who names these things?) laying eggs.

The Channeled Applesnail (Pomacea canaliculata) is a resident of the “Top 100 World’s Worst Invasive Alien Species.” Originally from South America, this snail can get up to six inches in size. Mama mia! Are we sure they are from South America and not Mars?

Experts believe that it arrived in the United States via the aquarium trade, and when it got too big for aquariums, it was released into the wild, a practice known as “aquarium dumping.” Established populations exist in Lake Wawasee in Kosciusko County, Indiana; Langan Park and Three Mile Creek in Mobile, Alabama; a pond bordering the Mobile-Tensaw River Delta in Baldwin County, Alabama; Little Wekiva River, Orlando, Florida; a lake near Jacksonville, Florida; Miramar Reservoir in San Diego County, California; and a pond near Yuma, Arizona. I can state with definitive certainty that it also exists in Lake Murray in San Diego County, which is where I got these pictures this morning.
