Volcanic Lightning

Volcanic Lightning is a weather phenomenon that occurs when lightning is produced in a volcanic plume. Rock and ash collide in the air after the eruption causing electricity to build up, when the charge is large enough it releases in the form of lightning. Volcanic lightning is hypothesized to occur from the site of eruption as a result of charge-separation.  As positively charged material is ejected skyward oppositely charged regions of particulars take shape creating electric discharge. If you would like to read more about Volcanic Lightning  there is a nice detailed article here on http://news.discovery.com/.
Whatever the bizarre cause of this rare event, it is defiantly one of the most beautiful and destructive sights this planet has to offer.

The Door To Hell

The Door To Hell

This flaming crater located in the Ahal Province, Turkmenistan near Darvaza has earned the name "The Door To Hell". In 1971, Soviet scientist identified the site as a possible oil field. A drilling rig and camp were set up on the now 230 foot wide crater.
The Soviets began drilling for natural resources. They found a natural gas deposit and began to store collected gases but for unknown reasons the ground collapsed under the rig, swallowing it in to the earth. Methane gas was released and posed an environmental threat, as well as a threat to nearby villages, which lead the scientist to the conclusion of burning off the deposit. The Soviets expected the deposit to burn off in a few weeks, however the crater has been ablaze for more than four decades and still burns to this day.

Eunice aphroditois (Bobbit Worm)

Eunice aphroditois

This is Eunice aphroditois, also known as the Bobbit Worm. This alien looking creature lives in the tropical ocean's near coral reefs. They seem to come in a variety of different colors and sizes. It has been known to grow to lengths of 10 feet or more.
The Bobbit Worm submerges itself in sand or soil on the ocean floor leaving only a few inches of its head exposed, ready to ambush any fish that may be unfortunate enough to come close enough for it to grab. As if that isn't disturbing enough, it then proceeds to grasp on to it's prey with the pharynx (mouth piece) at the front of it's head and pull it into the ground much like the graboids from Tremors. Talk about freaky, this thing is just plain out bizarre.

Even stranger than that, these subterranean serpents seem to have a knack for finding their way into salt water aquariums, more than likely brought in with rocks or sand as a juvenile and basically fed their own private stock of fish until adulthood. 
Here is a video of one feeding for anyone brave enough to watch. It's pretty astonishing.
