State of the art of reference genome availability for chelonians.

Species and subspecies are classified and divided into the main ecotypes (freshwater, marine, or terrestrial species). Estimated genome size is represented as Gb for all species. Assembly level represents the highest level for any object in the assembly (i.e., the sequence organization or connection among them). Sequencing technology is defined for every species jointly with N50, which indicates if the genome was sequenced using long-read (expressed on Mb) or short-read methods (expressed on kb).
