I know a close friend of mine who once did spearfishing under the flame on an oilrig (some 70km off shore). He told me that he was surrounded by a school of giant barracudas and it really got scary at the end when those barracudas wouldnt leave him alone
and he was the only one of the boat crew who dared to get into water. He noticed that fish were less warry and cautious than during daylight...
