How do whales deal with pressure?

Sperm whales can dive down to 2000m which is 200 atmospheres in pressure on top of its body. This problem is solved in some diving animals by lining the middle ear cavity with flexible material (Venous Plexus) that prevents a squeeze. Most marine mammals lack sinuses so they won’t have problems with them.

How do sperm whales handle pressure?

How do they survive the pressure encountered on a dive as deep as 9,000ft? Like many marine mammals, sperm whales have adapted to tolerate the effects of increased pressure when they dive in search of food. Sperm whales have a flexible rib cage to allow their lungs to collapse at depth and expand again at the surface.

How do whales survive long dives?

Whales have unique adaptations that allow them to go on long dives. They are capable of collapsing their lungs during dives to prevent damage from the increasing pressure. To further protect their collapsing lung, they have a jointed rib cage that allows their thoracic cavity to collapse with their lungs.

When a whale dives How do its ribs handle the increasing pressure?

Their ribs are bound by loose, bendable cartilage, which allows the rib cage to collapse at pressures that would easily snap our bones. A whale’s lungs can also collapse safely under pressure, which keeps them from rupturing. This allows sperm whales to hunt for giant squid at depths of 7,000 feet or more.

How do deep sea divers survive the pressure?

Scuba divers and free divers rely on equalising to prevent damaging their bodies. They compensate for static water pressure by adding equal gas pressure into their air spaces as the atmospheric pressure of the depth they are diving in. This prevents their air spaces from collapsing under pressure.

How do deep sea creatures survive the pressure?

Under pressure Fish living closer to the surface of the ocean may have a swim bladder – that’s a large organ with air in it, which helps them float up or sink down in the water. Deep sea fish don’t have these air sacs in their bodies, which means they don’t get crushed.

What happens when you fart in a scuba suit?

In theory, there should be no change to your buoyancy, as long as the fart gas stays in the suit. But a drysuit auto dump maintains a constant volume of gas in your suit, and by farting you’ve just added to the volume in the suit. Lose that gas and there will be a tiny drop in your overall buoyancy.

Why do whales need to dive so deep?

When diving to such great depths, whales face two challenges: storing enough oxygen to hunt successfully and withstanding the enormous pressure. High pressures change the uptake of gas in the body. Increasing pressure shrinks the air in the lungs and by 200 metres deep, both human and whale lungs will have collapsed.

What happens to whales when air pressure increases?

Increasing pressure shrinks the air in the lungs and by 200 metres deep, both human and whale lungs will have collapsed. This is the danger zone for whales.

How do whales breathe?

Whales spend most of their time underwater and use their surface-times efficiently. When they come up to the surface to breathe, they take several inhales and exhales before going for a dive again. When they inhale, the muscles around their blowholes relax, which closes their blowholes.

What are the anatomical adaptations for pressure of a sperm whale?

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.”
