Eden-DAoC

This night we were trying to find Megalodon. Searched for 2 hrs. Checked the red dot on the map. Checked every known loc from live, e.g. the ones from the german Daocpedia. Heard he moves counter-clockwise so we move clockwise. Even split up and waited at the locs and the red dot for 30mins if he comes across. Nothing.
Is there any loc or landmark where he can be found? Respawn-timer? He was killed 21hrs before we looked. Also, is his behaviour live-like (AE-Dots, Stuns and Shark spawns) so if we find him we are prepared?
Moreover, is there any other cloak with the Hibernian Cloak Skin on it apart from that one from the Megalodon quest? So that if we cant find him we have another chance to have the skin.

He does proc a bleed on the tank(not sure if aoe), he does spawn super tough redcon sharks. You also get zephyred. Tried twice with 24 peeps and got absolutely destroyed. It is likely we did something wrong.

He circles the entire zone counter-clockwise about as far from the zone walls as the dot is from it's nearest zone wall. If you swim go the dot and just go clockwise in a circle you'll find him without too much difficulty. He's a lot easier here than on live.
