Anything goes in The Snug, General Discussion's rebellious little brother. An off-topic den of iniquity where any subject not covered elsewhere may be discussed. Well, anything except golf, Star Wars and Arsenal.

No not able to breath water, why do you think that they have a hole on the top of their heads? It is for the snorkel, so that they can dive deeper than normal fish.... A bit like whales but smaller.

Must say I'm surprised Sendo,
But here you go....
Breathing requires an organ which is moist and has a large surface area. Fish gills are delicate structures, which, when removed from water, tend to stick together. This reduces the surface area available for gas exchange, meaning that they effectively suffocate since their gills can no longer obtain enough oxygen to sustain them.

Due to the electrical charge used to make up the picture? Get rid of.

There are some that can
The Climbing Perch can live 6 days out of water
The Lungfish can survive up to two years dug into mud without water
The Rockskipper comes out to catch prey or escape predators
Mudskippers can survive 3 days without water though they need to be moist and breathe through their skin

The food stuff has evolved in flavour over many thousands of years. When the plant was first discovered it smelt strongly of urine and as such was known thereafter as ginger.
