Half Pendant of Aquatic Endurance

The Half Pendant of Aquatic Endurance plays a large part in the druid quest Trial of the Sea Lion, part of the Aquatic Form quest chain.
When combined with the Half Pendant of Aquatic Agility, this creates the Pendant of the Sea Lion.

This pendant represents the ability to remain underwater indefinitely. For both tauren and night elves, you have to dive deeply for this, usually past the 'point of no return'. Fortunately, there are bubble fissures nearby where you can catch a full breath before continuing.
This item is found in different places for night elf druid than it is for tauren druids. Clues to its location are given by the druids in Nighthaven, Moonglade.
===Alliance: Longshore===
Swim out into the ocean from due west of Gold Coast Quarry. Head north a bit, and look down as you swim. Shortly before the ocean floor drops off into the depths (and the minimap displays a different color for the water), you should find a LARGE anchor. Swim down towards it and aim more west. You should see a bubbly fissure, with a Strange Lockbox nearby. The pendant half is in the box. 
If you swim over the bubbly fissure, your breath bar will be filled up.
There are a few elite sharks in the area before the drop-off. Be wary to avoid them.
You can also see a shipwreck in water only a little ways further out from this point. It is reachable, but there's not a lot to see there and it's in the fatigue zone.
Horde can also get this one too at 18, 33.
===Horde: Silverpine Forest ===
North of the Sepulcher is a beach with a large wreck on it. Head straight west from the wreck on the beach until you hit the drop-off (right about when you hit the "Great Sea" zone). Down at the bottom is a fissure where you can breathe, next to the fissure is the chest with the pendant half. You won't see the fissure/chest from the surface, so ... have faith. And hope.
