• There seems to be an uptick in Political comments in recent months. Those of us who are long time members of the site know that Political and Religious content has been banned for years. Nothing has changed. Please leave all political and religious comments out of the forums.

    If you recently joined the forums you were not presented with this restriction in the terms of service. This was due to a conversion error when we went from vBulletin to Xenforo. We have updated our terms of service to reflect these corrections.

    Please note any post refering to a politician will be considered political even if it is intended to be humor. Our experience is these topics have a way of dividing the forums and causing deep resentment among members. It is a poison to the community. We appreciate compliance with the rules.

'Killer Seaweed'

In the depths of the oceans live many species humankind doesn´t know anything about.

I once heard about a fish with a built-in light, or something.

Lots of things down very deep bioluminesce. There simply isn't very much natural light at all in the depths of the ocean so it is used for everything from attracting prey (as in the anglerfish cheezyflier posted) to seducing mates to warning away competitors to communicating. Some even use it to navigate.
