Millions of years ago, jellyfish were trapped in this lake after a submerged reef rose from the sea, creating a landlocked saltwater lake. In this lake, the jellyfish have adapted to the new conditions by losing their sting. They have eight primitive eyes and algae that live within their cells. These algae are what the jellyfish live on. Twice each day, the jellyfish in the lake swim from one side to the other. The jellyfish do this to get sunlight to their internal algae so that the algae can grow. At night the jellyfish swim to a lower depth where the water is rich in nitrogen. The nitrogen also sustains the algae population. The jellyfish has only one main predator in this lake – the sea anemone. Jellyfish can be stung, trapped, and killed by these creatures.
Humanoid Carp Found in Pond
The hybrid descendants of a carp and a leather carp (tangerine fish) are the new sensation in the small South Korean town of Chongju because of their “humanoid” facial features.
The look suddenly appears after observing the front part of their heads for a moment or two. Two lines and two dots on their heads bear some resemblance to human eyes.
Psychedelic bouncing fish
Via the Guardian:
A funky, psychedelic fish that bounces on the ocean floor like a rubber ball has been classified as a new species, a scientific journal reported.
The frogfish which has a swirl of tan and peach zebra stripes that extend from its aqua eyes to its tail was initially discovered by scuba diving instructors working for a tour operator a year ago in shallow waters off Ambon island in eastern Indonesia.
The operator contacted Ted Pietsch, lead author of a paper published in this month’s edition of Copeia, the journal of the American Society of Ichthyologists and Herpetologists, who submitted DNA work identifying it as a new species.
The fish which the University of Washington professor has named “psychedelica” is a member of the antennariid genus, Histiophryne, and like other frogfish, has fins on both sides of its body that have evolved to be leg-like.
(I do realise that this last one is a mammal and not a fish, but it fits under the subject)
Via the Torygraph:
The world’s only pink Bottlenose dolphin which was discovered in an inland lake in Louisiana, USA, has become such an attraction that conservationists have warned tourists to leave it alone.
Charter boat captain Erik Rue, 42, photographed the animal, which is actually an albino, when he began studying it after the mammal first surfaced in Lake Calcasieu, an inland saltwater estuary, north of the Gulf of Mexico in southwestern USA.
Capt Rue originally saw the dolphin, which also has reddish eyes, swimming with a pod of four other dolphins, with one appearing to be its mother which never left its side.
He said: “I just happened to see a little pod of dolphins, and I noticed one that was a little lighter.
“It was absolutely stunningly pink.
