It ’s just one of those fundamental things – all animals need water to survive . For us humans , get it into our body is as simple as drinking it . But what about fish ? They live in water , so are they just straight up engross it , or do they also take to salute ?
First thing first , Pisces can absorb body of water . This take place through a physical process calledosmosis , in water ’s attempt to achieve chemical equilibrium .
If that rings only a distant bell from the twenty-four hours of high school skill , let us refresh your storage ; it ’s the social movement of a solvent ( in this pillowcase , H2O ) across a semipermeable barrier from a neighborhood where there ’s a lower concentration of a solute ( in this showcase , salt ) to a area where there ’s a in high spirits engrossment .
However , whether or not Pisces also need to drink comes down to how much water is make or lost from their body via this process – and that depends on if they dwell in freshwater or seawater .
For freshwater Pisces , the fluids within their torso are much saltier than the water system surrounding them and so , seeking chemical balance , water is absorb through their skin and gills through osmosis .
As a result , freshwater fish generallydon’t needto toast much water – if they took in much more , the concentration of salt within their bodies would be so low that their muscles and skittish organization would n’t be capable to function properly . This is also why this type of fish pees reasonably much constantly , in lodge to get rid of supererogatory water .
Saltwater fish , on the other hand , do require to drink water to keep everything in equilibrium . pee is perpetually flow out of their less salty insides through their tegument and gills into the saltier surrounding water , so the Pisces the Fishes direct some of the piss that comes in through their mouth to the digestive tract rather than to the gills .
There ’s a problem , however . Whilst the water is very much need , if the intake of brine is left unchecked , there ’s also a risk of have too much salt in the organic structure – that ’s just as much an issue as have too little of the stuff . To prevent this , brine fish have specialized cells in their gills that pump salt out .
And if you ’re a shark , there ’s another elbow room you’re able to get rid of extra saltiness too – asalt secretory organ in the rectum .
So , there you have it – some fish do indeed drink . But did you make love that fish can alsoget drunk(as in drunk , we ’re not proposing a fish charmer ) ?
