The San Antonio River Authority is increasing its efforts to remove invasive apple snails from the San Antonio River, where the fast-reproducing species has threatened the river's ecosystem and spread by the thousands.

Apple snails are native to South America, but they have been found in growing numbers on the San Antonio River.

The river authority has worked since 2019 to remove the snails and their egg clusters, which can often be spotted on river walls and look similar to bright pink bubble gum.
