The genome sequence of the harbour porpoise, <i>Phocoena phocoena</i> (Linnaeus, 1758)

We present a genome assembly from a female specimen of <i>Phocoena phocoena</i> (harbour porpoise; Chordata; Mammalia; Artiodactyla; Phocoenidae). The genome sequence has a total length of 2,512.71 megabases. Most of the assembly (94.41%) is scaffolded into 22 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled, with a length of 16.38 kilobases.
