Popis: A pregnant salmon shark Lamna ditropis, captured in Alaska in December 2006, held two male and two female oophagous embryos (two per uterus) nourished by a single large 7·5 kg ovary. This discovery provides new data and insights into reproduction of the species and new perspective on the genus Lamna.
