10 Useless Shark facts

 1. The existence of Sharks are 100–50 million years older than the first trees

2. Sharks do not have bones, instead they are born with cartilage for bones because it is lighter.

This is also why so many shark fossils are just teeth.

3. Greenland sharks can live for 250 or even 500 years

4. The Whale shark is the biggest fish in the world

5. Hammerhead sharks mostly swim sideways

6. Cookie Cutter sharks latch onto prey and cut off flesh in a circle

7. Bull sharks can live in salt and fresh water

8. The Megalodon's jaws could grow this big

9. Lemon sarks wouldn’t actually eat lemons🍋

10. The Great White shark loses anywhere from 20,000 to 30,000 teeth in their life time

What is the most useless country in the world in terms of resources, economy, etc.?

 Most likely Tuvalu.

Tuvalu is an island nation in the South Pacific and midway between Hawaii and Australia in the Polynesian part of Oceania.

The entire country is 25 square kilometers with about 10000 people and the only occupation you can do in Tuvalu is fishing. Sadly for Tuvalu, tourism is not big here and it doesn’t have hotels and it is one of the least visited countries in the world.

The country has no water resources and nor does it have rivers or soil to cultivate anything so pretty much everything has to be imported.

Surprisingly, this country has a per capita GDP of over $6000 pp on nominal basis so I guess they must catch a lot of fish and they also generate revenue by issuing fishing licenses.

Essentially, Tuvalu is just a strip of land in the middle of the ocean with nothing in terms of natural resources except the ocean sorrounding it.

I don’t know if it’s a useless country but the entire country’s GDP is $63 million, probably less than what a single Costco generates in revenue in a year.

Rising sea levels also pose grave danger to this country and just like Maldives and Kiribati, Tuvalu is at risk of becoming the next Atlantis.
