During a field visit, one of the students observed a cyclindrical worm in the soil, and noted its characteristics like segmented body, bilateral symmetry and presence of clitellum. After its dissection , students observed that the worm was eucoelomate . Another student observed a worm which was thread-like without segments and after its dissection they found that the worm was pseudocoelomate. Based on the given paragraph answer the following questions. Which animal was observed by the first student ?
