Hippos can open their mouths to an astonishing 150 degrees—wide enough to show off massive teeth and powerful jaws. While it often looks like a big yawn, this display is usually a form of communication, helping hippos establish space and show dominance rather than an invitation for a snack. At the Cincinnati Zoo, seeing a hippo open wide is a jaw-dropping reminder of just how powerful these animals are. Big smile… big respect. | Cincinnati Zoo & Botanical Garden

Explaining on Instagram: "Zoo keepers clean hippos’ teeth by training them through positive reinforcement to open their mouths on command. Hippos are taught from a young age to stay still while keepers gently scrub their massive teeth with long-handled brushes, helping remove food buildup and prevent infections 🦛🪥 This routine is crucial because hippo teeth never stop growing and can develop painful issues if neglected.
