How do fish eat without swallowing water?

Do sharks chew or swallow?
Sharks don’t chew their food; they rip off chunks of meat and swallow them whole. They can last a month or two without another big meal.
How do whales not drown when they eat?
New UBC research may just hold the answer. Researchers found that lunge-feeding whales have an ‘oral plug’, a fleshy bulb in their mouths that moves backwards to seal off the upper airways during feeding, while their larynx closes to block the lower airways.
Do sharks get thirsty?
Instead of drinking water, the shark absorbs some seawater (and salt) through its gills. A glandin the shark’s digestive system gets rid of excess salt.
Can sharks choke on food?
“They can’t choke to death like humans since an esophageal block doesn’t restrict breathing in a shark,” he told the Los Angeles Times by email. “It’s most likely that the shark was rubbing along the seafloor to dislodge the food and the animal just stranded and couldn’t get back to deeper water.”

Do sharks get water in their mouth?
Sharks can slosh water around in their mouths to manipulate food to some extent, but swallowing is another matter. They may compensate by using the muscles of their pectoral girdle – the equivalent of our shoulders – that supports and powers the anterior ns during swimming.
Do sharks eat their babies?
Ovoviviparous shark pups depend on yolk for nutrition, and when an embryo has expended its own yolk sac, it turns to the eggs around it.
