   Hippos cannot actually swim — they sink and gallop along the riverbed, surfacing to breathe every few minutes.

   Orcas are actually the largest species of dolphin, and each pod hunts with dialects and techniques passed down like culture.

   It held the record for largest wingspan of any aircraft until 2019, yet flew exactly once, in 1947 — for about 26 seconds.
