If you have ever been in the sea for a long time have you ever noticed that your skin plumps up? Or if you are in fresh water like a bath have you ever noticed how your skin wrinkles.
These effects are caused by an effect called osmosis. Osmosis is when molecules of a solvent to pass through a semi-permeable membrane from a less concentrated solution into a more concentrated solution. Well that's the technical description.
Fish, molluscs and even Octopi who live in the sea have a huge problem. Their internal fluids are Less dense than the surrounding sea water. So they need to minimise their water losses and balance salt intake because the sea is leaches water from their bodies by osmosis. So to combat osmosis they don't urinate much and they have to have a way of reducing salt.
With fresh water fish the opposite is true they gain water all the time through their skins so they urinate all the time and don't need to drink. Their problem is the exact opposite of the Salt water organism.
So do Octopi get thirsty? Probably as its likely that they need to drink sea water and process it constantly.
No because you can't 'eat' water, you can only drink it.
Octopuses live in freshwater, salt water, and shallow water.
Octopuses breathe water through gills, not air.
No. Octopuses live in salt water, not fresh.
Yes, octopuses can breathe out of water. They have gills that extract oxygen from the air, allowing them to breathe when they are not in the water.
No, octopuses cannot survive outside of water for an extended period of time as they require water to breathe and move.
Octopuses can typically survive out of water for about 30 minutes to an hour, depending on factors such as temperature and humidity.
Yes, octopuses need water to survive as they are aquatic animals that rely on water for respiration, movement, and maintaining their bodily functions.
First the octupus catches its prey till it has full control over it. Secondly it bites it with its beak. The beak then makes its prey fall in a doze or sleep. Then since its prey does not try to escape the octopus eats it.
No, octopuses cannot survive on land because they require water to breathe and move.
No. The only group of animals that suckled milk from the mother are mammals. Octopuses are not mammals, nor even vertebrates.
Octopuses rely on extracting oxygen from water through their gills and do not breathe air.
