The jelly fish came to this lake in Palau through
a tunnel which connected the sea and the lake long
time ago. Now the tunnel have closed, and the
jelly fish came to have no poison in an
environment where there's no predator. They live
by photosynthesis because they cannot feed on
anything in this lake. This lake is such a heaven
to them that there are just so many of them living
here. Tags :jellyfishphotosynthesispoisonlakePalau
