Golden Jellyfish
Sky Jellyfish
在一个清晰,平静的一天,湖仍在允许直接在朝天空的水母下拍摄这张照片。金水母估计已经隔离了12,000年,因为湖只有一个捕食者(海葵),他们失去了刺痛的严重程度,使他们可以安全地接触人类。Snorkeler in Jellyfish Lake

水母湖in Palau
There is just something about jellyfish. Maybe we are drawn to them because they look so beautiful, with their long appendages and pink and purple colors, or how they move gracefully through the water as if they’re flying. Sadly, we know we can’t touch them or we will suffer the painful sting of their nematocysts. For all of us jellyfish lovers, there is a special marine lake in the Rock Islands of帕劳,被当地人称为ongem’l tketauand known to the tourists as水母湖, filled with a species of non-stinging jellyfish.
距离Koror大约一个小时的船,在Eil Malk Island上进行了短暂的徒步旅行,导致这个惊人的湖泊估计有超过1300万的金水母。我跳下了一个木制码头 - 让人想起我的童年夏季游泳 - 仿佛是世界上其他任何湖泊。
But as I swam out towards the center of the lake, away from the shadows of the surrounding jungle and into the sunlight, a few golden pink jellies appeared around me. As I swam to where the most sunlight shone on the lake, the number of jellies multiplied, and pretty soon I was bumping into them in front, behind, and below me. They were everywhere.
起初感觉很有趣。我的直觉告诉我不要触摸水母,除非我的好友在附近并需要使用洗手间!但是,不可能不对他们施加冲突,或者他们不要对我施加冲动。勇敢地碰到一个人,您会觉得它们就像果冻,光滑,但并非完全坚固。还有很多!
Snorkelling Only
Only snorkeling was allowed in Jellyfish Lake, as bubbles could get caught under the jellyfish bells and damage them. Because they relied on sunlight to help produce energy, jellyfish are found right at the surface. So why do they need sunlight? The jellyfish have symbiotic algae that live in their tissues that help them produce their energy.
In order to get the most from their symbiotic algae, the jellyfish migrate across the lake daily, following the sunlight. At night, the jellyfish move vertically from the surface to deeper waters, to acquire nitrogen and other nutrients for their algae.
The Golden jellyfish aren’t the only creatures in the lake; there are also moon jellyfish (Aureliasp.), cardinal fish, silversides, gobies, and the jellyfish’s only predator, anemones. An anemone will make dinner of a wayward jelly that ends up in its tentacles. But, by following the sunlight, it’s uncommon for the jellyfish to end up in the shaded areas at the edges of the lake, where the anemones live.
The金水母(Papua etpisoni) is thought to be a subspecies or the most closely related to the Spotted jellyfish (Mastigias papua), found in the nearby lagoons. Like the Golden jellyfish, the Spotted also have symbiotic algae living in their tissues, but the Golden jellyfish have lost their spots and most of their ‘clubs’, which are the appendages attached to the oral arms. You can encounter Spotted jellyfish on dives around the rest of Palau, but beware, they still刺.
湖本身非常独特。Still connected to the ocean through fissures and tunnels in the lime stone, it experiences slight tidal shifts. However, it doesn't seem that other organisms have found their way into the lake. The lake has two distinct layers: the upper layer being oxygenated, and the lower being anoxic, or oxygen-free.All organisms that require oxygen live above 50ft.
Dangers Below 50ft
随着硫化氢从湖底升起,湖泊的深度也可能对人类危险,而紫色光合硫细菌将含氧层与缺氧分离,并含有高浓度的氨和磷酸1zplay皮肤。这是禁止在湖中潜水的另一个原因。虽然靠近地面是完全可以的。
帕劳(Palau)至少有四个孤立的海洋湖泊有水母,每个湖泊都被认为足以成为其独特的亚种。1zplay但是,Ongem’l Tketau是唯一向游客开放的湖泊。水母湖的金水母仍然有刺痛的细胞(线虫囊),但他们的严重程度失去了严重性。无论如何,有些人仍然可以在嘴周围经历敏感性,因此那些对水母有严重过敏反应的人可能想穿防护服。
