Even so, Dunaliella salina has the capability to make massive amounts of beta-Carotene, the reason why this solitary-celled organism is capable to survive. The beta-Carotene assists the algae to defend by itself towards the intense daylight that is reflected off the salt, and also offers it the darkish pink hue.

There are even a few species of fish that survive in the saline water due to their ability to pump out further salt, keeping their h2o ranges balanced.
Salt Extraction
Unnecessary to say, the lake is also nicely-known for its salt generation. One particular can often see salt collectors at work near the lake. The shores are entire of salt piles, producing it a great landscape of white and pink when noticed from afar. This salt is collected by the locals basically by making use of their arms.
