This episode presents a captivating discussion with James Weiss on his team's significant findings in the diverse world of microbes. Despite many microbial species escaping detection due to their low numbers or dormancy, Weiss's team has discovered the extraordinarily rare ciliate, Legendrea loyezae Fauré-Fremiet, 1908, in freshwater anoxic sediments. This discovery represents the sixth account of the ciliate since 1908. The conversation dives deep into the species' unique morphological features, such as its "shapeshifting" ability to control the full extension and retraction of its tube-like tentacles. Weiss also questions the validity of certain taxonomic decisions and proposes reclassifications based on morphological characters and tentacle movement. This episode is a testament to the rewards of persistent exploration of natural habitats and the exciting possibilities it offers for uncovering new microbial species and communities.
