The alien hunt has begun

Although you might think that the most likely time to encounter creatures from outer space is in a dark night, we started our hunt for aliens in Tjärnö on a rather sunny morning. Armed with tools and dressed in chic wading pants and wetsuits we went out to start our search for non-native marine species.

Ready to hunt…
We chose to take a closer look at a number of man-made structures, such as the pillars which hold up the jetties in front of the typical Swedish boat houses, as well as rocky beaches on the shore of the bay. In this way we hope to find out which factors facilitate the spread and colonization of non-native species in the bay.

Potential landing sites for marine alien species – the pillars of jetties and rocky shore  
As the marine aliens can be hard to identify in the wild, because in some cases the non-native species only differ in small characteristics from a native species, we collected samples in the field and took them to the lab for identification. So during the next days at the Sven Lovén research centre we will use microscopes and bury ourselves in scientific books to determine all the organisms we have collected so far.

Taxonomy,Taxonomy,Taxonomy
In the next blog post we will reveal if we could detect some aliens in Tjärnö Bay. So stay tuned and follow our alien hunt!
