Yes, whales have earwax and yes, we have 1,000 samples of it in our collection.
Like the rings of a tree, these waxy time capsules give scientists a timeline of data about a whale's life and environment—opening up a whole new canal of ocean study.
This piece of whale earwax is among hundreds of rarely seen specimens and artifacts in #ObjectsofWonder, a new exhibition at our @smithsoniannmnh. It explores the breadth, scope and splendor of the world’s most extensive natural history research collection and its sometimes surprising role in scientific discovery. It’s open through 2019.
