Top best answers to the question «Do mammals have gills and can breathe underwater»
- Mammals do not have the ability to breathe underwater. Mammals that live underwater have to expose the top of their heads while resting or at the top of the ocean to get oxygen from the air. Fish breathe underwater with the help of their gills, which helps pull the oxygen from water instead of from the air. However, unlike fish and other creatures that live and breathe underwater, ocean mammals cannot breathe in the same way.

Those who are looking for an answer to the question «Do mammals have gills and can breathe underwater?» often ask the following questions:
🌊 Do all mammals have the diving reflex?
- All mammals have the diving reflex, including humans. The diving reflex is the body’s physiological response to submersion in cold water and includes selectively shutting down parts of the body in order to conserve energy for survival.
🌊 How are marine mammals adapted for shallow and deep diving?
- In summary, the primary anatomical adaptations for pressure of a deep-diving mammal such as the sperm whale center on air-containing spaces and the prevention of tissue barotrauma. Air cavities, when present, are lined with venous plexuses, which are thought to fill at depth, obliterate the air space, and prevent "the squeeze."
🌊 How can i teach my child to breathe underwater safely?
- Instead, take deep breaths through your nose, touching your nose to show where it is going in. Emphasize your control during the release with the motorboat noise—or by making up any game that you and your child enjoy. Gradually, move the release from your mouth to your nose and from the air to the surface and even slightly below the water.
🌊 How can marine mammals see underwater but we can't?
- Well, they have evolved to see things in the underwater world with the help of a larger, more spherical lens than land vertebrates. Additionally, there is very little difference in density between the fish cornea and that of the seawater, so there is very little refraction and focusing is left up to the lens.
🌊 How can whales and dolphins stay underwater for a long time without gills?
Whales and dolphins don't have gills
In contrast, dolphins and whales have a set of lungs like us, which means that they cannot breathe underwater. Owing to this biological necessity, such species have to surface frequently to get some fresh air.
🌊 How do marine mammals see underwater?
Where do marine mammals get their water from?
- Marine mammals have to get water from what they eat or from the sea. Whales actually drink sea water. I suppose that other marine mammals do this too. They have very big kidneys that can get rid of the salt without losing a lot of water.
🌊 How long can marine mammals stay underwater?
Sperm whales make some of the longest dives achieved by mammals, with some lasting up to 90 minutes, while dolphins and other whales can stay underwater for 20 minutes. The longest time a human has held their breath for under water is 19 minutes – set by a Swiss freediver called Peter Colat.
🌊 What adaptations do mammals have for diving?
- Increases in the concentration of respiratory pigment in the blood and in muscle are important adaptations in diving mammals. The blood oxygen stores in diving mammals vary from near normal to over three times normal for terrestrial mammals while the muscle oxygen stores vary from near normal to nearly ten times normal.
🌊 What are some types of underwater mammals?
- Here are some examples of general types of marine life that inhabit these ecosystems: Invertebrates such as crabs, worms, jellyfish, squid, and octopus Corals Fish, such as anglerfish and some sharks Marine mammals, including some types of deep-diving marine mammals, such as sperm whales and elephant seals

No, mammals don't have gills, and can't breathe under water. Mammals have lungs, breathe air and have to hold their breath when diving.

The A99 aquata breather, also called a Jedi breathing device, was a small breathing device consisting of a compact mouthpiece that could fit in a utility belt… Jedi Qui-Gon Jinn and Obi-Wan Kenobi used aquata breathers when traveling to the underwater city of Otoh Gunga on Naboo.What underwater mammals need oxygen?
- Seals, semi-aquatic marine mammals, store oxygen in their muscles and blood instead of in their lungs. This helps them to stay underwater for long periods. When they dive into the water, they breathe out instead of holding their breath like other mammals. There are four different groups of marine mammals.
- Kisame, the Monster of the Hidden Mist, had an abnormally high amount of chakra since he was born, so he's pretty tough. Because he can fuse with his sword and gain the ability to breathe underwater, Kisame will often create a gigantic dome of water in order to fight people for however long they can hold their breath.
- If the rationale behind the DR is to preserve intrinsic oxygen stores (FIGURE 1), it is especially important for diving aquatic mammals, which spend up to 80% of their time submerged (77, 95), to bank as much oxygen as possible. Indeed, diving mammals do this several ways.
Special properties of an oxygen-binding protein in the muscles of marine mammals, such as seals, whales and dolphins, are the reason these animals can hold their breath underwater for long periods of time, according to a new study… In fact, the amount was so high in the muscle that it almost looked black in color.Why do diving mammals have lower heart rate?
The normal dive response in marine mammals has long been understood to involve a marked reduction in heart rate (called bradycardia) and other physiological changes to conserve limited oxygen reserves while the air-breathing animals are underwater.
