B. the pseudocoelom that acts as a hydro skeleton causes the characteristic thrashing motion of nematodes.

  • The longitudinal muscles of nematodes are contracted to move them. The animal moves by thrashing back and forth because to the tremendous internal pressure that forces the body to flex rather than flatten.
  • Nematodes only have longitudinal muscles, not the two bands of muscles found in other worms.
  • They can only move by clenching the lengthy muscles on either side of their body and wiggling forward, which explains their distinctive thrashing motion.
  • The pseudocoelom serves as a lubricant between tissues, houses coelomocytes, and generates turgor-hydrostatic pressure for the entire animal.
  • Because it is fluid-filled, the fluid's hydrostatic qualities enable a more rigid construction, greatly improving the efficiency of the skeletal system and movement.
