The IX International Symposium on Tardigrada

The congress was attended by 48 researchers from 10 countries from four continents (Asia, Europe, North, Central & South America). During the three days of the conference 26 talks and 26 posters were presented.

So far, this was the third time that a tardigrade meeting took place in the USA, making it (along Italy) the top country for the number of tardigrade conferences. It was also the first Symposium in the XXI century.
