Here’s where it gets hilarious. Lobsters can take in air, but not by inhaling like a human. They do it by oxygenating their gills with air bubbles when they’re in low-oxygen water. Think of it as a lobster burp-ventilation system. In water that’s too warm or stagnant, they’ll stick their mouths and gill openings above the surface and gulp air, mixing it with water to keep breathing. Yes, they look like tiny, armored air-guzzlers.

I once saw a video of a lobster doing this in a tidal pool. It looked less like survival and more like it was arguing with the water. “This water is garbage,” the lobster seemed to say. “I’m going to the surface bar for a shot of oxygen.” Surprisingly, this behavior is common among burrowing lobsters that live in mucky, low-oxygen zones. They’re basically the snorkelers of the sea floor.

Wait, it gets weirder. Lobsters don’t even have a mouth in the way you’d expect. Instead of drinking air through a windpipe, they pull water (or air) in through little openings at the base of their legs called gill bailers. These tiny appendages—called scaphognathites (try saying that after three drinks)—beat back and forth like tiny windshield wipers to create a current. That current pushes water (or moist air) over their gills. It’s basically a crustacean fan system.
So, when a lobster is on land, it’s not really “breathing” in the lungy sense. It’s operating a weird, low-tech air pump through its leg armpits. You could say a lobster out of water is less a creature and more a portable, vaguely terrifying, retro-futuristic humidifier with claws.
