It wouldn't.
It would die almost instantly.
It is impossible for life to survive on Neptune for the following reasons:
Neptune does not have a solid surface and is mainly composed of gas. A creature on Neptune would not be able to breathe as we do on Earth, as there is no oxygen-rich atmosphere to sustain life. Any hypothetical creature living on Neptune would have to have evolved to extract necessary elements from the harsh conditions of the planet.
Living on Neptune would be inhospitable due to its extreme cold temperatures and lack of solid land. Therefore, it would not be possible to survive on Neptune and consequently, there would be no food source available.
There is no oxygen on Neptune, so, no. In theory, you may be able to in a space suit, but still, physically, no, you can't breathe on Neptune. Neptune is too cold to support life and too cold for electronic equipment to operate properly (such as space suits). See the related question below.
Yes. Neptune is extremely cold.
No. Neptune is cold enough that even a coat would not protect you.
Neptune is very very cold a coat would not protect you enough.
no the atmosphere is to thick on Neptune to breathe
You would look like a corpse. Life cannot be supported on Neptune.
if we lived on neptune we would be blowen round because winds blow at 2000 miles per hour and it is very cold
your a big old stupid head!
they would have either a lot of fur or body fat because the temp. on Neptune can get up to be -373 degrees F

The creature would be hobbit. They were shorter than dwarves and lived in the Shire.
you wouldhave to live in a cool house
its nearly impossible to live on Neptune since it's a gas giant but if you could you would probably need to fly and withstand very cold weather plus breathe with no oxygen
For any creature to be able to breathe, there has to be something to breathe. Space is vacuum, an empty nothing. No creature can get anything from nothing. So no, a turtle wouldn't be able to breathe in space. Unless you provide it with an atmosphere, like in a space station, space ship or a space suit. Then a turtle most likely would breathe just fine.
The gills would not function well because they need to get oxygen flowing through them to make the creature able to breathe.
