OK - for my last adventure of the day, I decided to try on of the numerous sea cucumbers lying around the reef. Asking around, Ira says he has heard of an export industry here, and although some Niueans eat the sea cucumbers, they prefer the smaller thinner kind is it was more tender. That at least gives me enough confidence that it's edible for me to try it. I found one of the sea cucumbers that looks close to what I've ate before and picked it up. It was surprisingly difficult due to its many working suction cups on it's bottom. Even placing it down for a minute on a rock on the shore caused it to get stuck quite tight to it. On the way back, I ran into Willy - he recons it's edible, but seems a bit unsure of it.
