Wikipedia describes Olive Sea Snakes or Aipysurus Laevis, to use they're latin name, as
'One of the Sea Snakes in the species that are reported to be the most aggressive and the most venomous'
Well i don't know where they got they're facts from but myself and Aaron found them to be pretty inquisitive and cool. Although they have a mighty punch with they're venom, I think it would take a lot to upset the good old Sea Snake.
But don't take my word for it, see for yourself.
