Picture of the week: So, who wants to take the plunge ...?
He's flying without wings – in a dive that goes straight down 27 metres into treacherous waters.
David Colturi is just one of the sea divers taking part in the current Red Bull Cliff Diving World Series.
This breathtaking dive took place from a specially-erected platform off the cliff face at the Islet Vila Franco do Campo in Portugal, the fifth stop in a series of events that have already taken place in Havana in Cuba, Fort Worth in the United States, Inis Mor in the Republic and Krager in Norway.
David and his fellow 23 competitors routinely make dives off platforms that are higher than competitive divers such as Olympic hero Tom Daley, for whom the highest board is usually only 10 metres.
Colturi is currently lying in eighth position in the event that also has eight female international divers competing.
The 25-year-old from Chicago, who is the former US 10-metre diving champion, says: "I'm so new to the sport still.
"I've been training my a** off and I'm going to try and keep getting better".
Gary Hunt of Great Britain is the current leader and has won the event three times over the last four years.
The 29-year-old's repertoire includes the triple quad, the first dive conceived exclusively for cliff diving, which packs in three somersaults and four twists and has a difficulty rating of 6.2 – the highest of any dive in the sport.
On September 20, the World Series will come to Spain for the first time, where 14 of the world's top sea cliff divers will once more dive off 27-metre high platforms.
Then the world's best cliff divers will travel to Mexico's Yucatan Peninsula for the 2014 final of both the men's and women's competition on October 17-18.
They will dive into the root-covered sinkhole close to the archaeological site of Chichen Itza, in Mexico, that hosted World Series competition previously in 2010 and 2011.
Ik Kil Cenote is a natural formation, which has assumed an almost mythical dimension.
It was once attributed sacred powers and, at 60 metres wide and 39 metres deep, it's certainly an impressive sight for spectators.
