Euglandina rosea (Férussac, 1821) Depositing Eggs In The Field |
On 3/7/2019 this specimen was discovered in the early stages of depositing an egg clutch in a swampy area on the west side of US-1 about 3.1 miles northwest of International Golf Parkway in northern St. Johns County, Florida. Only three ova were seen (see: Euglandina rosea Depositing Eggs In The Field ). The snail was checked two days later on 3/9/2019 it was still present at the exact same location and was still in the process of depositing eggs (see image below). The nail polish mark on the spire (the color identified by the manufacturer as "Bora Bora") is part of an experiment being conducted to ascertain the size of the Euglandina population as well as their movements within the study area. This specimen was initially tagged with the nail polish on 3/2/2019. |

The progress of the egg laying event was checked two days later on 3/11/2019. The Euglandina was no longer in the immediate area but the number of eggs deposited had increased to 38 (see below). Based upon experience, 38-40 ova per egg clutch appears to be the normal number deposited by an adult Euglandina. |
