Atlantic Herring Clupea harengus
A streamlined shoaling fish. The overall colouring of the body is silver but a darker blue iridescence is present over the upper half of the body. The body is deeper than it is wide, which improves the streamlined nature of the fish. Their fins are not bony, like in many other fish, but are soft. Image: Joachim S. Mùˆller (iNaturalist).
