Dallol - The World’s Weirdest Volcanic Crater:

In the North East of Ethiopia lies the Danokil Desert.  At its heart is a volcanic crater, Dallol, little known and seldom visited but quite extraordinary.  

Surrounding the volcano are acidic hot springs, mountains of sulphur, pillars of salt, small gas geysers and pools of acid isolated by salt ridges. It makes for one of the most bizarre landscapes on planet Earth.

They look like alien landscapes!

The clownish grin of a bridled parrotfish reveals its power tools: grinding teeth used to scrape algae from rock. Though sometimes destructive to individual corals, the fish’s efforts are mostly beneficial. Without them, algal growth could smother the reef. Scarus frenatus.
