| an accordion-like tube that contains sperm and is the site of oocyte fertilization. | spermatheca | WBbt:0005319 | |
| female genital. | vulva | WBbt:0006748 | |
| A chain of very large cuboidal cells forming a wide central lumen in which food arrives from the posterior pharynx, is digested, and from which waste products proceed to the rectum. Intestinal rings form in groups of two and four cells surrounding the common lumen; thus the epithelium is only one cell deep at any point, with neighboring cells firmly secured to their neighbors by apical adherens junctions. These cells have very large nuclei and many large vacuoles, yolk granules, and other inclusions; the latter increase in number and electron density as the animal ages. | intestine | gut | WBbt:0005772 |
| the feeding organ, a neuro-muscular pump in the head of the animal, used to ingest food, bacteria suspended in liquid, filter them out, grind them up and transport posteriorly into the instestine. | pharynx | esophagus | WBbt:0003681 |
| rectal gland cell | WBbt:0005799 |

|---|---|---|---|---|
| The stage that begins when a C.elegans individual is fully-developed and has reached maturity. | adult Ce | WBls:0000041 | ||
| The third stage larva. At 25 Centigrade, it ranges 32.5-40 hours after fertilization, 18.5-26 hours after hatch. | L3 larva Ce | WBls:0000035 | ||
| The second stage larva. At 25 Centigrade, it ranges 25.5-32.5 hours after fertilization, 11.5-18.5 hours after hatch. | L2 larva Ce | WBls:0000027 | ||
| The fourth stage larva. At 25 Centigrade, it ranges 40-49.5 hours after fertilization, 26-35.5 hours after hatch. | L4 larva Ce | WBls:0000038 | ||
| The first stage larva. At 25 Centigrade, it ranges 14-25.5 hours after fertilization, 0-11.5 hours after hatch. | L1 larva Ce | WBls:0000024 | ||
| The C. elegans life stage spanning 620-800min(hatch) after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. A stage after elongation is over. The last stage of embryogenesis. Also called pre-hatched embryo, late embryo or morphogenetic embryo. | fully-elongated embryo Ce | WBls:0000021 |
