Other Life Forms

The hyperdiversity that stems from geo-diversity as well as species migrations from the coast, north, and deserts yield at least 40 times as many fungi and bacteria that occur in the surrounding areas.

The Caves, streams, and rock outcrops highlights microbial diversity – moonmilk, cave slime and biofilms, “desert varnish,” lagoon microbial mats, diatom-covered stream cobbles, and cyanobacteria in marble.

Did You Know?

Scorpion under ultraviolet-DYK

Scorpions fluoresce or glow under ultraviolet (UV) black light. They can glow electric green or blue. Scorpions fluoresce because they contain a fluorescent protein in the upper layer of their exoskeleton. This layer is like your fingernail, but even more protective and tough. The special protein inside is thought by scientists to serve as an ultraviolet sensitivity mechanism, perhaps allowing the scorpion to avoid burning itself by staying exposed too long to damaging light levels.
