Few people ever observe the world's most prevalent animal, but scrutiny by University of Hawaii researchers may change the way scientists look at the little insect-like ocean-dwelling invertebrates known as calanoid copepods. The UH researchers have discovered that nerve cells of the species Undinula vulgaris are coated with myelin -- a substance generally thought to be limited, with very few exceptions, to humans and other vertebrates. If upheld, their findings, which are reported in the April 15 issue of the journal Nature, will require revision of basic biology textbook discussions of the difference between vertebrates and invertebrates.
