horny plates which hang from the roof of the mouth in some whales (Mysticeti), e.g. right whales and rorquals. The plates filter out krill (small shrimplike crustaceans) from the sea water as it is forced out of the mouth.
Edwin Foekema, co-author of one of the first studies showingthe presence of microplastic in the intestines of a baleen whale, believes most microplastics ingested by marine animals will naturally leave the organism, just as food does.
As a biologist, I especially enjoyed Dr Erich Fitzgerald's keynote about his work with palaeontology and baleen whales - it was very interesting and engaging, and is something I know my students would be interested in as well.
