Notes:
This item is an earwax plug from the Rorqual (Balaenopteridae) family of whales. Rorquals are the largest group of baleen whales (whales with baleen plates that serve as teeth, which help them feed on tiny plankton). Examples of species in the Rorqual family include: Antarctic minke; Blue whale; Bryde's whale; Eden's whale; Fin whale; Humpback whale; Northern minke; and the Sei whale. These whales build up the wax in their ear canals over time, which creates the earplug. The earplugs can be used as an aging tool, as indicators of the specimen's health and stress levels, and as indicators of the health of the specimen's ecosystem, through chemical markers that are present in the earwax. This specimen is embedded in acrylic. The ear wax plug itself measures approximately 7 cm x 2 cm x 0.5 cm in size.
