Orcinus Orca
The genome of the killer whale was sequenced from a female whale Morgan (https://www.ncbi.nlm.nih.gov/assembly/GCF_000331955.2/#/def), and a 2249-MB high-quality reference were assembled [3]. It has the following facts:
● Total assembly gap length: 123,337,750
● Number of scaffolds: 1,668
● Scaffold N50: 12,735,091
● Scaffold L50: 60
● Number of contigs: 80,100
● Contig N50: 70,300
● Contig L50: 9,480
