Caenorhabditis

Part of speech: noun

Definitions

1. A genus of nematode worms known for their transparency and use in biological research, particularly in genetics and developmental biology
2. This organism is often studied for its simple anatomy and ease of genetic manipulation, frequently serving as a model organism in laboratory settings
3. It is characterized by its small size, hermaphroditism, and well-mapped genome, making it an essential tool for studying cellular processes and behavior

Etymology: Caenorhabditis is a modern scientific coinage, not an ancient word, and it was built from Greek parts that describe the worm's appearance. The genus was named in 1900 by the German-American zoologist Ludwig Maurer? No, the genus was established by Émile Maupas in 1900, who was studying nematodes in France and needed a name for this group. The name combines Greek "kainos," meaning "new" or "recent," with "rhabditis," from Greek "rhabdos," meaning "rod" or "staff," a reference to the rod-like shape of these small worms. Caenorhabditis elegans, the species most people mean by the word, was later studied by Sydney Brenner in the 1960s, who chose it as a model organism because it is transparent, grows quickly, and has a small, fixed number of cells. That research earned Brenner, alongside others, a Nobel Prize in 2002.
