Or an old one in new positions? Watch this video and tell me what you think! I realize it's a myspace video so how much credit you give is entirely up to you. However, I think it's worth a quick look at least. http://vids.myspace.com/index.cfm?fuseaction=vids.individual&VideoID=37523121

I don't know how many of us have heard of the Colossal Squid, but some information is under the cut.
Here's a link to the Shell Purdido Project, which is how this footage was recorded. http://www.shell.com/home/content/aboutshell/our_strategy/major_projects_2/perdido/perdido_13032008.html

Tree spirit [Jul. 9th, 2008|09:46 am]

The first thing I thought was, "It's Jesus," LOL. A commenter on the story apparently thought the same thing. %^)

Meet the tree with a face
Is it a demon? A new Doctor Who monster? A bit of rubbish art? No, it's a section of an oak tree branch that looks like a human face. Sort of.

The face-tree was brought into the Daily Times newspaper in Maryville, Tennessee on Monday, by Ernest Ward, a groundskeeper at the local Magnolia Cemetery.

Ward said it was found on Monday as he and co-workers cleaned up debris from a weekend storm.

According to him, a former worker at the cemetery believes the face is a spirit.

Greta oto - the glasswing butterfly [Jul. 9th, 2008|01:31 pm]

wtf_nature = stress relief. Greta oto says -- why be camouflaged when you can be invisible?

This family of south-American butterflies (ITHOMIIDAE) has wings that are completely transparent, like panes of stained glass. They also taste bad.



From Wikipedia:
"Greta oto is a brush-footed butterfly, and is a member of the clearwing clade; its wings are transparent. Its most common English name is glasswing, and its Spanish name is "espejitos", which means "little mirrors." Indeed, the tissue between the veins of its wings looks like glass. It is one of the more abundant clearwing species in its home range, which is found in the amazon rainforest (South America) The opaque borders of its wings are dark brown sometimes tinted with red or orange, and its body is dark in color. Its wingspan is between 5.5 and 6 cm.

Adults range from Mexico through Panama and inhabit the rainforest understory and feed on the nectar of a variety of tropical flowers. G. oto prefers to lay its eggs on plants of the tropical nightshade genus Cestrum. The red and purple striped caterpillars feed on these toxic plants and store the alkaloids in their tissues, making them distasteful to predators such as birds. They retain their toxicity in adulthood. The same alkaloids that make them poisonous also are converted into pheromones by the males, which use them to attract females.

G. oto adults also exhibit a number of interesting behaviors, such as long migrations and lekking among males."

and:

"Ithomiines are unpalatable because their adults seek out and sequester pyrrolizidine alkaloids from plants that they visit, especially composit flowers (Asteraceae) and wilted borages (Boraginaceae). The slow-flying adults are Müllerian mimics of each other as well as of many other Lepidoptera. Identification of adult ithomiines relies on hindwing venation and male androconial scales (sex brushes located on the hindwing costa).

The group has repeatedly been proposed as biological indicators of ecological conditions or biological diversity within neotropical forests, but individual sites harbor between 10 and 50 species, for the most part, and beta diversity is often great, even over relatively short distances."

Rubik's Cube used to get on right side of octopuses

It may be an infuriating puzzle which has baffled and defeated countless children and their parents over more than two decades, but this octopus appears determined to solve the Rubik's Cube.

The three-dimensional puzzle, which became a huge success in the early 1980s, is among toys being given to the intelligent sea creatures to determine whether they favour a particular tentacle, or if they are octidextrous.

Experts believe octopuses use a preferred arm for feeding and touching objects and will test the theory with a month-long observation project in Sea Life Centre attractions across Europe.

Itsa beetle. [Jul. 9th, 2008|08:39 pm]

Bombardier Beetles are ground beetles (Carabidae) in the tribes Brachinini, Paussini, Ozaenini, or Metriini—more than 500 species altogether—that are most notable for the defense mechanism that gives them their name: They can fire a mixture of chemicals from special glands in their abdomen.

Bombardier beetles store two separate chemicals (hydroquinone and hydrogen peroxide). When they are threatened, the two chemicals are squirted through two tubes, where they are mixed along with small amounts of catalytic enzymes and undergo a violent exothermic chemical reaction. The boiling, foul-smelling liquid partially becomes a gas (flash evaporation) and is expelled with a loud popping sound.
