| No | Do hirudiea what a fluid filled coelom? |
| Shedding old skin | What is ecdysis |
| Ecdysone | What is the molting steroid hormone called? |
| No | Does phylum menatoda have cilia? |
| It allows the animal to resist external pressure | Nematoda: why is the pseudocoelom water filled? |
| The pseudocoelomate and cuticle... aids in circulation and the dispersal of nutrients | What makes up the hydrostatic skeleton in nematoda? |
