What is it about?
We analyzed the microbes that live in the body wall of the marsh slugs and compared them to those of other mollusks. Remarkably, we found that similar groups of organisms are present in all mollusks regardless of their species, ecosystem, and tissue analyzed, although diversity was detected when they were studied more in depth at the genus level. This highlights a substantial opportunity for the discovery of previously unknown host-microbe interactions in these slugs that are gaining importance as laboratory models to study regeneration and other aspects of their life.

Why is it important?
This species provides a good opportunity to study aspects of slugs that have been poorly studied thus far or not studied at all. The knowledge we have generated on their anatomy, their genome, and now on the microbes that live in their body, are useful reference resources that could allow any research group anywhere in the world to start studying them.
Perspectives
It amazes me all the different and relevant aspects we can study on these slugs from our backyard. We are slowly building a research platform for this species that is originally from Europe and is now present near all the major urban areas of the world and, hence, could be the basis for research programs and teaching science worldwide.
