Pomacea canaliculata (Lamarck, 1822) In Upper Reaches Of Julington Creek In Duval County

    During a terrestrial snail survey in Duval County on October 30, 2014, this reporter discovered a single Pomacea canaliculata in the upper reaches of Julington Creek where the creek crosses underneath Philips Highway (Route US-1). This site is known locally as the Freedom Commerce Center Tract [located just north of the Avenues Mall and east of US-1]. When first spotted crawling in the creek (image below, inset), the snail was believed to be a very large Pomacea paludosa (Say, 1829) Florida Applesnail since this species had previously been found at this location (See: Freedom Commerce Center Tract, Southeastern Duval County, Florida). However, upon retrieving the specimen from the water it was discovered to be a Pomacea canaliculata. No additional specimens, either living or empty shells, could be found. It should be noted that this reporter has visited this site on a periodic basis since 2003 and no previous evidence of Channeled Apple Snails had ever been found.

Postscript: Following the find of the single snail during October, 2014 the site was revisited on an irregular basis for almost six years and no additional evidence of Pomacea canaliculata was seen. Finally on 10/15/2020 a single fresh egg clutch was found on the concrete box culvert pictured below indicating that a viable Pomacea canaliculata population is still present.
