Not sure whether the mobile phone pictures are going to work out for this or not. [YEP - now finally OK!]
If they do, they are of a small jellyfish that I can only describe as a Box Jellyfish. Box shaped head, with 4 very distinct long streaming tentacles. They actively feed on small fish, worms etc attracted by wharf lights where my boat is kept at Rose Bay. Once their tentacles hit the fish, they seem to be poisoned and the tentacle then retracts it up into the box/head section, where it is quickly comsumed.
I have seen them many times over the years, probably at this time of year rather than summer.
Does anyone know what they actually are?
I had the impression that true box jellyfish (ie: sea wasps & irukandji) were only evident in Northern Australian waters, but in googling the subject and looking at pictures, the appearance is eerily similar to the irukandji variety.
