Sepac 2018: Spectacular View
The common theme of the 13 countries issuing Sepac stamps is “Spectacular View“. The motif on the Icelandic stamp is Vestrahorn, a strikingly beautiful mountain in southeastern Iceland. Vestrahorn’s very impressive peaks reach up to around 454 m and are girded by steep, imposing cliffs. Vestrahorn is one of the few mountains in Iceland made almost exclusively of gabbro with occurrences of granophyre. It is located by the open ocean, about 10 km east of Höfn in Hornafjörður.

Seabed Ecosystem III: Sponge
Sponges (Porifera) are multicellular organisms which differ from all other multicellular organisms both with regard to structure and physiology. The sponge depicted on the stamp lives in Icelandic waters but has not received an Icelandic name. The Latin term is Mycale lingua. Sponges take in their food in an unusual way because they do not have mouths like other multicellular organisms. They draw water through innumerable pores in which choanocytes, cells covered with cilia, feed on organic debris particles and microscopic life forms. In the course of one day sponges can draw several litres of seawater through these pores, thus receiving sustenance. Sponges are in all likelihood the oldest multicellular organisms in the story of evolution.
