Spirostomum (Ciliate) I found it in a canal. 😍🔬

"Spirostomum is a genus of ciliated protists in the class Heterotrichea. It is known for being very contractile."...."They are identifiable by their relatively (to other ciliates) large tubular/flat vermiform bodies. Their life cycle consists of a growth stage, in which they mature, and asexual and sexual reproduction stages.[6] Some species are model organisms for studies on human pathogenic bacteria, while others are sensitive and accurate bioindicators for toxic substances." - Wiki
