Many people don’t know! Why do sharks have to swim all the time? Otherwise, would they really drown?
When it comes to marine predators, many people immediately think of “sharks”. They are fierce, fast, and scary in the eyes of many. But did you know that sharks also have a “weak point” that many people never knew before? That is, some species of sharks “must swim all the time” or else they may suffocate. Sounds contradictory, right? Real aquatic animals, but if they don’t swim, they can “drown”.
This time, Campus has gone to find information to answer many people’s doubts about why sharks must swim all the time, otherwise they will drown.

Generally, marine animals breathe with gills, which filter oxygen from the water that passes through their bodies. However, some sharks do not have a “pumping mechanism through the gills” like other fish. Therefore, these sharks swim all the time to allow water to flow through their gills so they can breathe. This สมัครสมาชิก UFABET วันนี้ รับเครดิตฟรีทุกวัน method is called Ram Ventilation. Simply put, if a shark stops swimming = water does not pass through the gills = no oxygen = cannot breathe, at risk of death from lack of oxygen.
But not all sharks have to swim all the time. Some sharks, such as nurse sharks or some species of hammerhead sharks, can use the method of “pumping water into their mouths and through their gills” like other fish. This allows them to “lie still” or “stay still” without dying.
Why did nature design it that way?
One of the main reasons is “hunting”. Sharks are high-energy hunters. Their Ram Ventilation breathing system allows them to swim fast, move continuously, and not have to stop breathing like other fish. But in exchange for the disadvantage that they “can’t stop”, it’s like turning on automatic hunting mode all the time. If you get tired and stop = it may end your life.
