What else can I help you with?
Tortoise can stay in the water sometimeHow does tortoise do that?
Tortoises can hold their breath underwater for extended periods of time by slowing down their metabolism and conserving oxygen. They can absorb some oxygen through their skin and cloaca while submerged, which helps them stay underwater for longer periods. Additionally, tortoises are able to store oxygen in their body tissues, allowing them to survive underwater for extended periods.
Why does a platypus's heart rate must slow down so it can stay underwater for long periods of time?
so it has a longer time of having air
What are the benefits of using a small scuba breather for underwater exploration?
Using a small scuba breather for underwater exploration offers benefits such as increased mobility, ease of use, and the ability to explore deeper depths for longer periods of time.
Why did Jacques cousteau invent the aqualung?
Jacques Cousteau invented the Aqua-Lung to allow divers to explore underwater for longer periods without needing to surface frequently for air. This invention revolutionized underwater exploration by providing divers with the ability to breathe underwater using compressed air tanks.
How long can snails breathe underwater and what adaptations do they have for this ability?
Snails can breathe underwater for a few hours to a few days, depending on the species. They have gills that extract oxygen from water and a thin layer of mucus that helps them absorb oxygen. Additionally, some snails can store oxygen in their tissues to survive longer periods underwater.
What breakthroughs has jerry achieved by the story's end?
By the end of the story, Jerry has achieved breakthroughs in his ability to hold his breath underwater for longer periods of time, his bravery in exploring the underwater tunnel, and his understanding of the importance of independence and self-reliance.

How does a diving bell work and what is its primary function in underwater exploration?
A diving bell is a chamber that traps air, allowing divers to breathe and work underwater. It is lowered from a ship and creates an air pocket for divers to enter and exit. The primary function of a diving bell in underwater exploration is to provide a safe environment for divers to work at greater depths for longer periods of time.
What are the benefits of using hot water diving suits for underwater exploration?
Hot water diving suits provide several benefits for underwater exploration. They help maintain a comfortable body temperature in cold water, reduce the risk of hypothermia, and allow divers to stay underwater for longer periods of time. Additionally, these suits can improve mobility and dexterity, making it easier for divers to navigate and manipulate equipment underwater.
How do the sea nomads hold their breath for extended periods of time while diving underwater?
Sea nomads, also known as the Bajau people, have developed a genetic adaptation that allows them to hold their breath for longer periods of time while diving underwater. This adaptation includes larger spleens, which help store more oxygen-rich blood, and changes in their diving reflex, which slows down their heart rate and conserves oxygen. These biological traits enable the sea nomads to dive and hunt underwater for extended periods without needing to come up for air as frequently as others.

You won't have to deal with idiotic questions much longer.
Why do you have brown periods when on birth control?
