NO. They can be found anywhere a lake is. Such as water.
Most leeches require permanent fresh water to survive athough a few species can survive in damp soil. Therefore the only places a leech could survive in a desert are in an oasis, river or other source of permanent water.
no
Only about 1.7% of earths water is drinkable fresh water, so conserve it! Most of the fresh water is found in glaciers
The only medical instrument that would have been used when a doctor used leeches was a knife. Leeches are small parasites found in water. They suck blood, so sometimes a doctor would cut a person before adding the leeches.
Volvox and all of its close relatives are found only in freshwater.
~71% of the earth is covered with water, of that ~97% is salt and ~3% is fresh (2% of fresh water is frozen, only about 1% is available)
Only 2.5% of Earth's water is considered fresh water (i.e. not in oceans). Most water is in our oceans.
Water is considered as a scarce resource as fresh water occupies only 3% of total water found on earth.

only 3% is fresh water
Only about 3% of Earth's water is fresh. Two percent of the Earth's water (about 66% of all fresh water) is in solid form, found in ice caps and glaciers. Because it is frozen and so far away, the fresh water in ice caps is not available for use by people or plants. That leaves about 1% of all the Earth's water in a form usable to humans and land animals. This fresh water is found in lakes, rivers, streams, ponds, and in the ground. (A small amount of water is found as vapor in the atmosphere.)
