On this week’s Nature Sunday, I bring you Jellyfish Lake. What? a place?
Jellyfish lake, or Ongeim’l Tketau (local Palauan name meaning “Fifth Lake”) is a marine lake located on Eil Malk island in Palau.
Jellyfish Lake is connected to the ocean through fissures and tunnels in the limestone of ancient Miocene reef. However the lake is sufficiently isolated from the neighbour lagoons. This condition reduces the diversity of species in the lake. The lake is mainly occupied by millions and millions of Golden Jellyfish (Mastigias cf. papua etpisoni). Another resident of the lake is the Moon Jellyfish (Aurelia sp. Despite)
One cool thing about these jellyfishes is that because of the lack of predators, sting cells are no longer needed. And through the course of evolution, their stingers have gotten so mild that it can’t be felt by human touch.
My laptop has such a temper. He has be constantly giving me the the beach ball of death for the last 2 weeks. Just when I started looking into getting a new laptop, he starts working fine again >=[. It’s like he is playing with my emotion =[.
This week we have the Kakapo (Strigops habroptila) from New Zealand, it is also known as the owl parrot.
The Kakapo is the heaviest specie of parrot in the world. Is is also the only flightless parrot.
The Kakapo is critically endangered. In the past, because of the isolated environment and absence of mammalian predators, it lost the ability to fly. However, during Polynesian and European colonisation, predators such as cats, rats, ferrets, and stoats were introduced into the environment, the Kakapo was almost wiped out.
Now the surviving Kakapo are kept on three predator-free islands, Codfish (Whenua Hou), Anchor and Little Barrier islands, where they are closely monitored.
The Butcher Bird is native to Australasia. It has a large, straight bill with a distinctive hook at the end which is used to skewer prey.
Butcherbirds are insect eaters for the most part, but will also feed on small lizards and other vertebrates. They get their name from their habit of impaling captured prey on a thorn, tree fork, or crevice. This “larder” is used to support the victim while it is being eaten, to store prey for later consumption, or to attract mates.
