Euglandina rosea (Férussac, 1821) Eggs And Egg Laying (Page Three)

Case Study Number Three

    During the morning of 9/12/2011 the 57.2 mm. specimen pictured below was discovered in the process of depositing eggs in its makeshift terrarium. The specimen had been taken into captivity in Duval County, Florida on 4/25/2011 and maintained in solitude for over one month prior to the event. The egg laying continued for approximately 48 hours and ultimately 49 calcareous eggs were deposited. This specimen was involved in case study number two chronicled on the previous page. On 9/31/2011 the Euglandina subsequently expired.

    On 10/11/2011, almost exactly a month after they were deposited, the eggs began slowly hatching. By 10/14/2011 24 of the 49 eggs had hatched, and by 10/16/2011, all but one of the remaining eggs had hatched. The remaining egg was discovered to be unembryonated. All 48 juveniles were released into the wild during the evening of 10/17/2011.
