Sarsia siphonophora II (B 657)

Sarsia siphonophora (B 657) II 
2012 watercolour 
(ca 55 x 75 cm)
The previous entry showed a detail of the colony building jellyfish species Sarsia siphonophora.

In this blog I present an impression of the complete animal.
This image is of course not true to life: everything (shapes, curls, colours) is exagerated for great effect.

Apolemia uvaria (B 201)

The Blaschka glass model 201, portraying Apolemia uvaria, was based on a figure printed in one of Carl Gegenbaur's articles: "Beiträge zur näheren Kenntniss der Schwimmpolypen (Siphonophoren)", published in: Zeitschrift für wissenschaftliche Zoologie, Band 5. (pp 285-344. Taf. XVIII, Fig. 1). This journal was published in 1854. His illustration shows a young individual of this siphonophore species. Blaschka copied the image, translated it into glass, and a copy of this model was sold to the University in Liège. This in turn served as  an example for this study in watercolour.
