But, if caught by net or hook and line and rapidly hauled to the surface, a Draughtsboard Shark may sometimes inflate with air instead of water. The cardiac sphincter renders the Draughtsboard Shark's stomach reasonably air-tight. When the sphincter relaxes, trapped air passes out the shark's stomach in an explosive rush, creating a hoarse 'bark' as it goes. So, at least one shark, the inflatable Draughtsboard Shark from New Zealand can produce sound. But I think there's something deeper here.
Many people admire sharks because, no matter what they're doing, they look so cool doing it.
But no matter how cool they are, even sharks are not immune to the occasional noisy belch. Copyright Rick Martin.
