Natural History Redux
I promise this is the most amazing 30 minutes you will spend this month. This is the free 720p version.
The full 1080p version is available for $5 here. I guarantee the HD is worth it, and all proceeds go directly to reef restoration! I am personally working on the supported project, and once again it is 100% worth $5.
Puffers, man, They’re all the rage…
Puffer fish, when provoked, protect themselves by releasing a nasty toxin that can be deadly. But the dolphins appear to have figured out how to make the fish release it in just the right amount.
After chewing on the puffer fish and passing it around between one another, the dolphins appeared to enter into a trance-like state.
"[T]hey began acting most peculiarly, hanging around with their noses at the surface as if fascinated by their own reflection," noted zoologist Rob Pilley. "It reminded us of that craze a few years ago when people started licking toads to get a buzz, especially the way they hung there in a daze afterwards. It was the most extraordinary thing to see."
The behavior was recorded on camera by the makers of the nature documentary, Dolphins: Spy in the Pod — a series produced for BBC One. Here’s the trailer: http://www.youtube.com/watch?feature=player_embedded&v=rBSatvvKVOo
What Is Lake Vostok?
by Becky Oskin
Deep, dark, and mysterious, Lake Vostok is one of the deepest subglacial lakes in the world.
Buried under more than 2 miles (3.7 kilometers) of ice near Vostok research station in Antarctica, the lake filled before Antarctica froze 15 million years ago, researchers think. Covered with ice for millennia, cut off from light and contact with the atmosphere, Lake Vostok is one of the most extreme environments on Earth.
The freshwater lake may harbor a unique ecosystem of microbes and other creatures that evolved in isolation for hundreds of thousands of years. These “extremophiles" could mimic life on other moons and planets, such as Jupiter’s icy moon Europa. Only meltwater from the overlying icesheet and drainage from Antarctica’s subglacial waterways have touched the lake since it froze over during the Miocene period. This constant replenishment means the water in the lake may be only as old as the ice that melts to form it, some 700,000 to 800,000 years, according to ice cores. But the true age of the lake water is unknown…

Jewel Anemone’s belong to a group of anthozoans and are not true anemones. You can most often find them on underwater cliff faces.
cool fact: they reproduce by splitting in half creating 2 new identical anemones.
…. All anemones are anthozoans…
Jewel Anemone: a cold water coral (Corynactis viridis)
Also, they are a type of corallimorph (order corallimorpharia) a kind of evolutionary link between corals and anemones which also includes mushroom corals (discosomatidae) and ricordea (ricordeidae)
