A fish can live without water…!!!
Yes, kids. This how wonderful our earth is.
Let me introduce you to Mr. Lungfish.
A South American Lungfisg. Found this from http://www.ucmp.berkeley.edu/vertebrates/sarco/dipnoi.html
Today, we can fonly find lungfish in Africa, South America and Australia.
So, what make this fish so special that is can survive without water.Some lungfish can survive in dried up rivers for weeks or months.
Well, in waters lungfish use their gill to respirate or breathe. If the rivers dried up, the air will go throughh a lunglike organ called a swim bladder. This is because the swim bladder consist a lot of tiny blood capilary or in general terms blood vessels which act as lungs. (As we all know,
exchanges of oxygen and carbon dioxide happen in our lungs). Thus gas exchanges happen in this swim bladder thingy and our lungfish friend can keep pon surving without waters.

There are several advantages to shopping online, the first one being the ability to shop at a time that is convenient to you, not just when the shops are open. The second advantage of shopping online is that goods are often cheaper as the seller does not have the costs of running a shop and having to pay wages to salespeople, insurance and all of the other running costs of a real world business.
