The mouth is bowhead shaped. It has no dorsal fin and is seen as two humps from above the water. The coloration is black with white cin patch. The baleens are dark gray to black with a silvery shimmer. There are 350 pairs that are up to 4.5 m long and 36 cm wide.

Humans and killer whales.
They migrate within their habitat (from summer feeding to wintering areas) rather than seasonally moving to more temperate waters like other great whales do.
Social system/Group size
Usually seen solitary or in groups of 2 - 3, but larger groups may be formed to feed or to migrate.
Habitat degradation, pollution and illegal hunting.
The WWF documents and protects critical feeding areas.
The Bowhead whale has the longest baleen of the mysticetes: 4.5 m. Also, the females are bigger than males in this weird sexual dimorphism.
