| Epidermal layer. | hypodermis | epidermis | WBbt:0005733 |
| a rigid external coating which is secreted by the hypodermis, seam and some transitional epithelial cells which covers the outer body, the major openings into the body cavity from the exterior, and two large sensory bristles, the male spicules. The cuticle of the spicules, the hook, and of some portions of the spicule channels is especially rigid and is probably sclerotized. Similar sclerotic features are occasionally noted in the ventral surface of the male tail fan. | cuticle | exoskeleton | WBbt:0005755 |
| Small linear ridges running along the lateral lines of the cuticle, lengthwise along the body; these thickenings lie in register with the seam cells which likely produce them and are present in the cuticle of the L1, dauer and adult stages, but not in other larval stages. The alae are suspected to provide better traction when the animal generates a bodywave. Since the animal usually lies on its side, the alae are in perfect position to catch against the substrate. | cuticular ala | alae | WBbt:0007832 |
