Oocytes of a single individual of Phallusia mammillata (Roscoff, France) were fertilized by a mixture of sperm of two individuals and development was followed microscopically. Embryos were snapfrozen in liquid nitrogen at the appropriate stage and kept at -80°C. Samples at stage 0, 8, 12, 15, 21, 26 were collected from the same fertilzation, while sample from stage 11 was independently collected from a different individual. Total RNA was prepared with the RNA II kit of Magerey Nagel and the quality was checked with the Bioanalyzer, all samples had a RIN value of higher than 9. Strand specific libraries were constructed and the sequencing (50PE) was performed with Illumina HiSeq 2000 technology (BGI, Hong Kong, China).
