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 kept in Ethanol alcohol in a glass jar. The smallest specimen measures approximately 10 cm x 4 cm x 1.5 cm in size, while the largest measures 13 cm x 4 cm x 1.5 cm in size."}, {"label": "Number of objects in this record", "content": "5"}, {"label": "Record Last Modified", "content": "1 Oct 2020"}], "name": [{"label": "Discipline", "content": "Vertebrate Zoology"}], "publisher": [{"label": "Scientific Name", "content": "Balaenopteridae"}], "topic": [{"label": "Topic", "content": "Education & Outreach"}], "place": [{"label": "Collecting Locality", "content": "Locality unknown."}], "physicalDescription": [{"label": "Sex", "content": "?"}], "taxonomicName": [{"label": "Taxonomy", "content": "Animalia, Chordata, Vertebrata, Tetrapoda, Mammalia, Artiodactyla, Mysticeti, Balaenopteridae"}], "objectType": [{"label": "Object Type", "content": "Education and Outreach collections"}]}}, "url": "edanmdm:nmnheducation_13081984", "hash": "456d5bec85a75be19d2b9a6c33c239780a31e8c3", "docSignature": "e08c0a9ce19b76168b919bb2ab63796c", "timestamp": 1663781097, "lastTimeUpdated": 1653682059, "title": "Baleen Whale, Rorqual"}
