Table 3 Single Nucleotide Polymorphism (SNP) numbers for several shark species (the white shark, Carcharodon carcharias, the bull shark, Carcharhinus leucas, the tope, Galeorhinus galeus, the basking shark, Cetorhinus maximus, the porbeagle, Lamna nasus, the shortfin mako, Isurus oxyrinchus, and the spurdog, Squalus acanthias). SNPs were called against the genome of C. carcharias, and filtered in three subsequent steps. SNPs were counted either for the whole genome, or for pre-selected target regions only. For sample information, see Table 1 and Supplementary File 1.
