Aquatic center lake Pomacea with misshapen abbreviated operculum |
|
|
The illustrated 78
mm. specimen, with no apparent operculum, was collected from the
aquatic park lake on 11/15/2006. Later, when the animal was
extracted from the shell, it was found to have a hard growth
attached to the front portion of the foot (bottom three images) -
apparently representing the snail's original operculum or a later
attempt to regenerate a lost operculum. A specimen with a similar
misshapen abbreviated
operculum had previously been found in St. Marys, Georgia
on 7/21/2006. Interestingly, a juvenile Channeled Apple Snail with no apparent operculum was previously collected in Duval County, Florida; was taken into captivity, and subsequently grew a normal operculum (See: Paper mill pond Pomacea with no operculum). |
