Morphology and Anatomy:

Nematodes of the genus Spirura are characterized by:

•  their cephalic structures
•  the esophagus in two parts: a longer muscular anterior region and a shorter glandular region.
• having a ventral projection or boss in the anterior region of the body, close to the glandular region of the esophagus
• the species of the Spirura are in two groups determined by the distribution of caudal papillae in males:
  • more primitive species with 8-12 precloacal papillae
  • more evolved group with 4 pairs of precloacal papillae
