Jellyfish Lake Philippines
If you have ever heard about Palau in Indonesia, then you probably are familiar with their Jellyfish lake. If not, then it’s for sure that you will put it on your bucket list.
Palau is the most beautiful place in Indonesia because it holds a rare attraction that lures visitors every year. It is the Palau jellyfish lake.
Those who are wondering as to where is jellyfish lake in Palau- it is in the Eil Malk, Rock islands, Palau.
This lake is the home for millions of jellyfish. There are two types of species living in the jellyfish lake Palau- Golden and Moon.
The typical jellyfish flow with the current without any directions to follow. However, the golden jellyfish floats across the lake back and forth every day.
Whilst the lake is the centre of attraction in Palau; is situated within the most isolated ecosystem. The jellyfish lake Philippines linked to the ocean through cracks and tunnels in the limestone rocks of a primitive Miocene reef.
Jellyfish Lake Age
Based on the thickness and depth of the lake it is estimated that the jellyfish lake Palau is 12,000 years old. The rising sea level has gotten to the point where it started filling the lake gully, and it took place 12,000 years ago.
Lake Jellyfish Species
The golden jellyfish are so closely related to the spotted jellyfish that occupy nearby lake. They are so similar that they obtain half part of their food from symbiotic algae and half food from zooplankton.
However, the golden jellyfish are different from the spotted jellyfish in many aspects, i.e. morphologically, behaviorally and physiologically.
The golden jellyfish doesn’t have as many spots on their exumbrella as the spotted jellyfish, and also the amount of clubs in their body has receded.
Michael Dawson, a marine biologist, suggested that the golden jellyfish that lives inside Palau Jellyfish Lake should be categorised as the subspecies of the spotted jellyfish inhibiting in the close by lakes.
The species is not yet been identified and is unknown. Alongside he also proposed that the jellyfish that’s living in 4 other Palauan lakes were exclusive enough to earn recognition as rare subspecies.
The scientific name for the moon jellyfish is known as Aurelia Aurita by Hammer. Nevertheless, since the 1981 report of the genetic testing of Aurelia’s specimens,
it indicated that besides the three named species of Aurelia there are another other six cryptic species in the Aurelia subdivision. The three of the cryptic species that discovered was from Palau.
Before you start thinking of going scuba diving with these species in the jellyfish lake in Palau, then I’m afraid you might have to tell you to scrap that thought out of your mind.
Because the scientist warns that the population of the jellyfish is in danger and slowly these species are getting extinct. Also, the deeper anoxic surface of the lake contains hydrogen sulphide, which is extremely poisonous to humans.
Freshwater Jellyfish Lake
The freshwater jellyfish are as small as the size of a penny, pellucid and slimy blobs that occupy lakes, streams, rivers and ponds in Pennsylvania. In the freshwater jellyfish lake, they do bite people.
However, their stingers are very tiny which doesn’t infiltrate human skin. The scientific name for the freshwater jellyfish is Craspedacusta Sowerby, and they categorised under an invasive species. Other biologists like Sarah Stahlman put them in a non-native species department.
Irrespective of their classification, the Ontario ministry of natural resources & forestry reported last year that the Lake Erie seems to have been invaded by the freshwater jellyfish in Lake Erie & Lake St. Claire.
According to biologist Sarah Stahlman, the freshwater jellyfish are fond of slow moving and still waters. And these species are of two forms; Polyp forms & Hydromedusa form.
She explained further about these two forms as Polyp form wouldn’t recognise by humans as they can be asleep in sediment for the longest of time. They seem to be more in the eastern zone of the US.
However, in Pennsylvania, they are all over the place. It depends upon the temperature. You’d see Hydromedusa more on the warmer temperature waters.
These jellyfish lives at the bottom of the lake as polyps which consider as an early stage in the species life cycle. Scientists are optimistic that if the lake’s situation improves, a new generation of the Hydromedusa would produce.
Most of the researchers and authorities deduced that the freshwater jellyfish lake doesn’t raise any threat to humans. Though, few experts urged that the future of the lake’s unique ecosystem might be in jeopardy due to climate changes.
Regardless of these claims and significant news, I would recommend that one should go and explore the jellyfish lake Indonesia before they get extinct entirely.
Keeping in mind that the tourists can no longer swim with the golden jellyfish, Kakaban Island came with an alternative to Palau where it offers its tourist to swim with four different species of jellyfish that have developed without any stingers.
