Abstract

Here we report for the first time on a loggerhead turtle, Caretta caretta, which laid 92 eggs on the south-west Italian coast on 11 July 2002. During the 64 day incubation period the nest was threatened by inundation and hence, it was transferred on the 28th day. The hatching success was 49.4% and all live hatchlings entered the sea. Unhatched eggs were opened to determine at which developmental stage embryonic death occurred. This analysis confirmed that most of the embryos died in the first few days after laying and that the transfer of the nest did not affect embryonic development. This was the third of three unusual nesting events in the western Mediterranean in the years 2001–2002.
