Reply to comment by [deleted] in TIL strawberries, raspberries, and blackberries do not qualify as “berries” as defined by botanists, yet kiwis, bananas, and tomatoes do. At least blueberries are indeed berries. by Aequitas05

How many other “fish” have no gills? Oceanic mammals typically aren’t at risk of drowning, as they can easily float for hours at a time and hold their breath for crazy lengths, too.

Not really. Humans can hold their breath as long as dolphins.

Turtles drown routinely from running out of oxygen. As do marine animals.

Living in the ocean is safer for ocean living surface breathing animals because they are thermally adapted, and a good measure of airway protection so that when they are at the surface they are not drowned by water in their throat (this is what drowns humans) but surface breathers live at the same knife edge as humans do it in the water, and can drown just as quickly if they are kept from the surface.

Eeeeeeh not to be that guy but on average, dolphins can hold their breaths for 8-10 minutes. Humans are closer to 2 minutes tops, some as low as 30 seconds, and that's not including people who just freak out when their heads are submerged...

The only people who can only hold their breath for two minutes are people who have never practiced it.

Ask a free dive instructor about how long it takes a classroom of average students to learn to hold their breath for more than two minutes even when they max out at 10-20 seconds their first try.

We are talking about capabilities here, and dolphins do not have the deep diving abilities that whales and sea lions and elephant seals do.

They have about the same capabilities as humans.

But we're talking average people vs. average dolphins...

You are. I am talking about the capabilities of the species

Dolphins are in motion they entire lives even when they are asleep.

For most of human existence until we started exploiting fossil fuel to become WALL-E human tubs of lard, we exercised at least 8 hours a day.
