Here in Blighty the chance of being bitten by a boa constrictor isn't too great, but on the island of Gorgona you could feel like a voodoo doll within five minutes.
It's like a reverse Ireland; there are snakes everywhere. Here Nigel recounts his encounters with wild boas, why a boa bite is better than a dog's, and which of the island's inhabitants took on the Spanish Conquistadors.
Oh, and Nigel? There's a spider on your face. Just thought we'd mention it.
We've all had holiday romances and Nigel Marven is no exception, because during this tour of Colombia he kisses a hummingbird. They are such flighty sorts.
Apart from admitting to puckering up to one of nature's most delicate creatures, Nigel also told us what makes Colombian hummingbirds so special and why dentists would shudder at their diet.
All those years marvelling at the realism of the 1997 B-movie Anaconda have been wasted, as Nigel Marven's explanation of how these fearsome snakes devour their prey is very much at odds with how the snake in the film trashed Jennifer Lopez's boat.
