Up shit creek - inside Martin Strel's wetsuit

A Slovenian endurance athlete known as the Fishman has completed a 3,000 mile swim along the length of the Amazon.

The Fishman also known as Martin Strel had to avoid crocodiles and sharks and had his team chum parts of the river with blood and raw meat to keep the piranha fish away.

But the Fishman's most terrifying Amazon enemy was the toothpick fish which is attracted by urine and enters the body through the penis where it extends spiked barbs and begins eating.

"I never urinate straight into the water, I always urinate straight into my wetsuit" says Martin.

According to the Guardian he also suffered from high blood pressure and diahhorea.

Christ knows what the inside of his wetsuit must be like.
