The trick with painting crustaceans seems to be to capture the expression of their faces, to make them look semi-opaque here and there and render them a soft underwater gloss on other parts. These are known by their scientific names Corophium volutator, Pallasea quadrispinosa, Palaemon elegans, Pandalus borealis, and Nephrops norvegicus.

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.

The carp family comprises some 2,400 species worldwide. Its members have no teeth and no stomachs! Instead they chew the food with their rakers of the specialized last gill bow against a plate formed by a procession of the skull. That way they can eat hard baits like snails and bivalves. The picture shows a few of the Bothnian representatives: asp, dace, rudd, ide, and silver bream, all drawn for the Havet homepage that I've mentioned in a couple of previous posts.
