Since the 1980s, Waite has overseen many discoveries about the incredible properties of bloodworm jaws, but Wonderly was particularly interested in the role of melanin, a type of pigment, as a major component of these unusual body parts. Wonderly is the latest in a line of researchers who have worked with these temperamental worms at UCSB’s Waite Lab, led by biochemist Herbert Waite, who is the senior author of the study. The results identified the crucial role of a specific multi-tasking protein (MTP) in the “impressive wear resistance” of bloodworm jaws, a finding that holds “tremendous potential for bio-inspired and natural materials processing,” according to a study published on Monday in the journal Matter. Now, scientists led by William Wonderly, a graduate student at the University of California Santa Barbara, have solved some of the open questions about how and why these animals evolved this mouthful of copper.
