“This is murena. Means ‘moray eel’ in Russian. It’s not a fish. Some say plant, some say animal, a really primitive one. It’s a thing. We call it murena because of what it does. The moray eel will hide in its lair. You never even know it’s there. It sits quietly underwater until a fish swims by, and then pow!” He grabbed a fistful of air. “It shoots out and bites the fish. It has a second mouth inside its throat, and that mouth shoots out and sinks onto the fish with hooked teeth.” He raked the air, holding his fingers like talons.
