Hippos have the largest mouths on land, can open their jaws 180 degrees, have an average gape of four feet, and teeth over two feet long, according to Guinness World Records.
The investigation into hippos' mouths reveals varied support from sources. Hippos do have the largest terrestrial mouths, corroborated by Guinness World Records. They can open their mouths wide, but not fully 180 degrees, typically reaching around 150 degrees. Evidence suggests the average gape of hippos is less than four feet, aligning with a 1.2-meter measurement. Hippos' teeth can be nearly two feet but not consistently over it. The evidence aligns with some claims but disputes others, reflecting a generally accurate but partially exaggerated collective claim.
