I know this isn't really the right place to post this, as this is not a boa, but while we're on the subject of wild snakes in Fiji, here's a shot of the sea snake we see quite a lot on dives. This is the White-lipped Banded Krait, Laticauda colubrina.
We see them underwater a lot, and on land usually at night, when they come up to digest meals, shed, and lay eggs. They also sometimes climb up our outboard engines to bask on the boat when we're out at sea, and this freaks divers out considerably...
They are (extremely) venomous, but small mouthed, back fanged and very docile, having no use for a strike reflex underwater, and having no natural predators. I handle them regularly (and with respect) when encountered. Note the flat tail which is adapted to be used as a paddle underwater.
As I said, no real relevance to a boa group, but I just think they are very beautiful, and hope you enjoy the photo. Can't think of a way to keep them without an olympic sized swiimng pool at my disposal though.....
