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.
