Table 1 Sampling details and DNA sequencing output for seven shark species. For sample details, see Supplementary File 1, for details on sequencing output see Supplementary File 3. Shown are average numbers per species and standard deviation. Initial reads were 151-bp paired-end reads. Reads and bases that survived cleaning and filtering prior to and after mapping (see Material and Methods) were taken as high quality (“HQ”). Genome sizes were taken from Stingo et al. (1989), Hardie and Hebert (2003), Marra et al. (2019) and Wagner et al. (2023). Genome assembly size for Isurus oxyrinchus from Stanhope et al. (2023) was not included in coverage calculations.
