River lamprey

Jawless fish branched off from other fish before the foremost gills of the latter turned forward to form the jaws. In addition they differ from others by not having paired fins or a stomach. They also sport a cartilaginous skeleton and a light sensitive pineal eye. This is a River lamprey, a species found in European rivers.

Vilket ordförråd du har/bygger upp på engelska! :-) Imponerande!

Thanks a lot, Francisco!

Tack, Malin! Men ordförrådet är egentligen inte mitt. Jag kollar facktexter på nätet och skriver ihop nåt utifrån det.
