5-millimeter needle hooks
HERNÁN VÁZQUEZ MIRANDA, WILDLIFE GENOMICIST AT UNIVERSITY OF NEBRASKA, LINCOLN
When we prepare mice and voles for preservation, we have to clean up their delicate skeletons. So we let 2-millimeter-wide dermestid beetle larvae eat the flesh inside the skull and around the ribs. After the bugs grow up and then die, we carefully remove them with needle hooks. You can’t get these tools at Walmart, so many are handmade—and that’s hard work. When a researcher makes a perfect hook, they treasure it for the rest of their life.
