They are even cooler because they have been cataloged and are still out there in the wild. It was neat to think the tsunami did it, but even better to know science did it.

The R/C Man said:I recieved these in an e-mail.... They look pretty cool so I wanted to share them regardless of there true origins..... You know how e-mails are....
Like I said: from an e-mail....
You never know what is true or not.... They are some cool looking critters though. What stands out right away is the large eyes adapted for the dark environment...... Oh and the very large teeth..... lol
That'll be enuf to keep you up at nite!!!
The photos are a hoax...photos were taken during expeditions in May-August of 2003 and specimens were captured during deep sea trawls at depths of up to 2000 feet. They are true animals, but did NOT wash up as a result of the tsunami.

All I know is I gotta have some of em....I think I'll start a "deep water" tank......anyone know how deep of a tank IAP can build???? U-G-L-Y

I was curious about that since none of the science was right about them washing ashore from Tsunami. Waves will break in half their height of water....eg..a 20 foot wave will break in 10 feet of water. Meaning that in 20 feet of water, you wont see the wave, it will be a swell, nothing more. So if these waves were 35 or slightly more, they would drag anything up from the benthic regions of the oceans. I was taught in my highschool oceanography and marine bio classes that shortly before a Tsunami hits , (we're talking seconds) the water will rapidly recede, lower than a really low tide which will leave some critters exposed...but animals like this shouldnt have been exposed under these conditions.
Neat pics under any circumstance though.

hold on to your wallets, judging by some of those mugs, the deep sea seems like a pretty dangerous place.

After thinking about it, I may need to do some research to find out how much pressure those animals have exerted on them at such depths. Anyone know the formula off hand?

While doing some searching I found this interesting artical below..... I pulled it from this site: http://servercc.oakton.edu/~billtong/eas100/oceans.htm
"Ocean Life
It may surprise you to learn that life is much more abundant in cold ocean waters than in warm tropical waters. In fact, warm tropical waters are considered aquatic "deserts" as far as life is concerned. The reason for this is due to the relationship between gas solubility and temperature. Most aquatic organisms need dissolved oxygen in water in order to survive. Gas molecules, including oxygen, vibrate more quickly in warmer water than in cold, and are more likely to escape into the atmosphere. For this reason, cold water usually contains more dissolved oxygen than warm water. Thus, cold ocean water supports a larger and more diverse food chain. Whales usually frequent polar waters in order to feed on huge swarms of phytoplankton and zooplankton, which are mostly tiny shrimp-like creatures.
An upwelling is a vertical movement of cold, nutrient-rich water brought up from the depths to mix with warm, surface ocean water. Winds blowing away from coastal areas creates ocean currents that can induce upwellings. Upwellings are important to the life cycles of fish and other sea creatures that need the periodic influx of food and nutrients.
Wind drives ocean currents, which are large-scale circulation patterns of the water. As you may seen in maps shown in the textbook, clockwise circulation of ocean currents is seen north of the equator, while counter-clockwise circulation is seen south of the equator. Ocean currents are also influenced by differences in temperature, salinity, and density of sea water. In general, cold, saltier water is denser and found at greater depths than warm, less salty water. Sometimes, the differences in temperature, salinity, and density are so dramatic that the ocean water actually separates into two layers; the boundary layer resists immediate mixing between the two types of sea water. Salinity is usually controlled by the amount of evaporation vs. precipitation, as reflected by climate at particular latitudes.
Life zones by ocean depth:
Photic Zone (0 - 100' depth, penetrable by sunlight)
Dimly-Lit Zone (100' - 2,000')
Twilight Zone (total darkness, below 2,000')
Hadal Zone (extreme depths below 15,000' - such as marine trenches)
Sea creatures may also be classified by their life style:
"Swimmers" are called pelagic.
"Crawlers" who live on top of or burrow into sediments are called benthic.
Deep-sea creatures are specially adapted to a dark, cold, high-pressure environment, where little food is available. They tend to have:
Large, light-sensitive eyes (or they may not need eyes, and are blind)
Disproportionately large jaws or teeth as compared to their body size
Red or black color
Some creatures even glow in the dark (bioluminescent), and are equipped with "headlights" or "fishing lures."
Ocean resources include: aquaculture (commercial cultivation of sea animals and plants), mineral resources (metals, salt, etc.), energy resources (petroleum, tidal energy, etc.), and even fresh water (icebergs)."

Greg,
As you go down in the ocean waters, you can roughly figure 44 lbs per square inch pressure, for every 100' you descend.
So... if these were only found at a depth of 2,000'... they would "only" of been used to approximately 88,000 lbs per square inch... pressure on their bodies.
I nominate them all, for the Strong Man Category!! *Grinz*

Kind of makes ya wonder.....What the heck else is in the sea?????

Wow Ed!
I think you moved the decimal point over to far..
I came up with 890 pounds per square inch.... I based my caclulations from the info below... Please double check it for me....
"We often speak of pressure in terms of atmospheres. One atmosphere is equal to the weight of the earth's atmosphere at sea level, about 14.6 pounds per square inch. If you are at sea level, each square inch of your surface is subjected to a force of 14.6 pounds.
The pressure increases about one atmosphere for every 10 meters of water depth. At a depth of 5,000 meters the pressure will be approximately 500 atmospheres or 500 times greater than the pressure at sea level. That's a lot of pressure. "
1 meter = 3.28 feet

Gregg,
You're very correct!!! I'm BAD BAD BAD!!!! that is 880ish lbs per square inch... but I still stand with my nomination! *Grinz*
