Candiru also known as toothpick fish, is a parasitic freshwater catfish native to the Amazon River. Although some candiru species have been known to grow to a size of 16 inches (~41 cm) in length, others are considerably smaller. These smaller species are known for an alleged tendency to invade and parasitize the human urethra.

Some Russian guys who have a passion for heights found one very tall radio tower and climbed it. They, of course, took pictures to show their climbing and how breathtaking and dangerous it can be at the same time.
Here’s this 270 meter high radio tower situated in Moscow area.
Well, even though I’m not afraid of height, I wouldn’t climb there even if my life depended on it ;)
