Actually, at no point do humans EVER have "gills," or even "gill slits." This common misconception was started in the early years of medicine. There are visible creases on the fetal neck that were originally thought to be remnants of past evolutionary stages. It is now known and commonly accepted that these creases are due to the formation of lymph nodes and lose visibility as the fetus matures.

What is the ability to breath underwater called?
The ability to breathe underwater is typically referred to as gills in aquatic animals such as fish, or as artificial devices like scuba equipment for humans. Humans do not have the natural ability to breathe underwater without assistance.
Do octopuses have gills for breathing underwater?
Yes, octopuses have gills that allow them to breathe underwater.
Could humans evolve gills?
It is highly unlikely that humans could evolve gills, as this would require drastic and improbable genetic changes. Humans are adapted to breathe air, and developing functional gills would involve significant alterations to our respiratory and circulatory systems. Additionally, the evolution of such a complex trait would likely take millions of years, if it were possible at all.
Why don't whales have gills for breathing underwater?
Whales are mammals, not fish, so they do not have gills for breathing underwater. Instead, they have lungs and need to come to the surface to breathe air.
Why humans drown in water and fish suffocate on land?
Humans drown in water because our respiratory system is not adapted for underwater breathing and we cannot extract oxygen from water like fish can. Fish suffocate on land because their gills cannot extract oxygen from the air, which is less dense and has a different composition than water. Additionally, fish need to stay moist to allow their gills to function properly, which is why they suffocate when exposed to air for extended periods.
Why don't grasshoppers have gills?
As grasshopper don't live underwater they don't need gills.
How can fish live in water?
They have gills which enable them to breath underwater.
Do you need to have gills to breathe underwater?
Yes, you do need gills to breathe underwater. Gills process the water through them that makes the water allowed to go through the animal's body without drowning them. Gills are the only thing that keep the animals that live underwater, alive. they also don't make you breath the air in-you breath the oxygen in the water!
Why can't a fly live underwater?
It doesn't have gills and has to breathe air.
Why does fish have to live in water?
They don't have lungs, they have gills. In simple terms, they don't have the right 'equipment' to breathe on land. Just like humans can't breathe underwater.
How long is a giant scorpion?

Does seahorses have a gill?
There gills are located at the back of their heads
Why can't you live underwater?
People can not breathe water. We have lungs rather than gills.
What fish characteristics do seahorses have?
Seahorses are fish that live underwater and breath with gills, and have fins.
Which of these adaptations enables a fish to live underwater?
Gills are the adaptation that enables a fish to extract oxygen from water and release carbon dioxide. This allows fish to respire efficiently while living underwater.
