Scientists announced today Jan. The announcement comes nearly two years after researchers aboard the British research vessel James Cook crowded around video monitors and became the first humans to glimpse an extraordinary sight 3 miles 5 kilometers below them, at the bottom of the Caribbean Sea: slender, rocky spires towering 20 feet 6 meters above the seafloor, spewing forth a sooty jet of metal-rich fluid some 3, feet 1, m high. It was an overwhelming moment of marvel at our world," said marine biologist Jon Copley, with the University of Southampton in England. The revelations from the expedition, published today in the journal Nature Communications, come at an exciting time. An expedition is at sea this week , aiming to take the first temperature measurements of the deep-sea vents, and take an even wider variety of samples.
Total Fat Finally, have you ever tried breeding these shrimp in Volcanic shrimp, high PH freshwater? Their main food is zucchini, green beans and my xhrimp maid frozen food. This was not the alga that appears in freshwater aquariums. The shallower of the two vents, dubbed the Von Damm, lies 7, feet 2, m down, near the summit of an underwater mountain Volcanic shrimp Mount Dent. They've grown substantially and have good color.

During the life shrimps produce small amounts of waste products: carbon dioxide, ammonia, nitrites and nitrates, which, in turn, are a nitrogen fertilizer for plants in this case - for the lower algae. Following the laws of the nitrogen cycle, nitrite are converted into less toxic nitrate by nitrifying bacteria that inhabit the soil and organic surfaces piece of driftwood , and nitrates are absorbed by lower algae.
The algae, in turn, produce the light necessary for life shrimp oxygen, etc. I was surprised and puzzled. As a person skilled in maintaining the biological balance in open ecosystems - aquariums - I not only did not deny the possibility of the existence of closed ecosystems, but emulated such systems in my aquatic rooms not once, creating aquariums that require virtually no interference for operation.
My surprise was based on the fact that a stable ecosystem can exist being of significant size. In a large aquarium significant variations of basic parameters are possible, such as water temperature, pH, hardness, level of dissolved substances. For example, if a fish dies and go unnoticed in a small aquarium, its decomposing will lead to increase in ammonia levels and rapid growth of bacteria that cause a decrease in dissolved oxygen in the water and similar processes.
These processes will not be so significant in a large aquarium. The same amount of ammonia and bacteria in a large aquarium will cause only minor changes that will be easily eliminated by the ecosystem itself: snails consume a significant amount of decomposing organic matter, and all that remains that is not eaten will be processed by plants, bacteria and filters.
Ecosphere of liters in size, in my opinion, has no right to exist; the biological balance in such a small volume cannot be sustained. The only explanation for this phenomenon in my view is the uniqueness of shrimps that leave in the sphere. Although I never had any experience with the inhabitants of salt and brackish water, I decided to buy these shrimps. These shrimps also tolerate temperature variations from 50 to 90 F 10 to 33 C , the lack of food for many months and even years!
During hungry period they can decrease in size that is, a new shell, worn them when molting is less than the previous one. I searched the Internet and found just one seller in Hawaii that sells wild-caught shrimp.
I have had a negative experience acquiring other "wild" shrimp in the past, but I was intrigued and impressed with their vitality, so I decided to buy. I was lucky: shrimps were alive despite such extreme shipping conditions. Now my goal was to create the right conditions for them, and that's what I want to share with you in detail to keep the reader from the possible mistakes, some of which I made myself.
Salt inhibits the growth of harmful bacteria and improves slime producing in discus, which is especially important during the feeding of discus babies, and promotes healing of wounds. Label on the bag have read that the salt is a common sea salt obtained by evaporation of sea water in the open sun. Its non-toxicity has been tested by me thousand times on discus. I left shrimps swimming in the open jar in the water in which I received them, netted out three "kamikaze" and put them in the freshly prepared water.
Shrimps were swimming normally within an hour or two, but then they became apathetic and stopped swimming. I touched them with a stick and found that they were barely alive. I immediately returned them to the jar with other shrimps. It was obvious for me that the problem was with the new water that was bad for the shrimps. I took another salt from Wal-Mart that is sold under the name Aquarium Salt.
The result was exactly the same as with the salt from Home Depot, with the difference that "kamikaze" were put in the new water overnight and found dead in six hours. I have carefully examined them with a magnifying glass and did not see any signs of life. However, I did not throw them out, but transferred in the jar to the other shrimp. I was surprised when, after half an hour they showed signs of life, and an hour later they began to swim.
I lost only one shrimp. Next day after work I visited a pet store and bought a pack of salt for salt water aquariums. This time there were no problems, and in two days after the arrival my new inhabitants have moved to the new residence.
Java moss was alive for two weeks, Elodea - a week, Java fern - a few days. Bacopa lasted longest. It even developed a few roots and leaves, but a month later began to wither and eventually died. I was quite resigned to the fact that in my tank with Hawaiian shrimps will be no live plants when I found a small patch of filamentous algae. This was not the alga that appears in freshwater aquariums.
Soon I found that this alga is growing quickly, and shortly it formed a pretty decorative tight ball. A year later, the ball has reached a diameter of inches cm , and I divided it in half, after setting up a new aquarium in my office at work. At first I set an aquarium with quartz neutral gravel. Then I got an idea to add to the aquarium landscape of live rock. This is known that over time, porous rocks are colonized by beneficial bacteria, which begin to take active part in the nitrogen cycle of the aquarium, in other words, they begin to act as biofilters.
I remembered that in nature Hawaiian shrimps live in lava cracks filled with mixture of sea and rain water. I was not sure of the complete inertness of red lava, so I set up a tank with lava bottom inhabited with low-value freshwater shrimps. I was sure that eventually some of Nerits hatched, but after a while, I found that I was wrong: the snails turned out to be regular Trumpet snails which perfectly adapted to salt water.
Taking into consideration that Hawaiian shrimps live in ecospheres for months and even years without any food, I knew that feeding them is not really priority number one in freshly established tank.
That's what I did for a while, but then began to experiment with other types of food. We must remember that Hawaiian shrimps are herbivorous. I crushed ramshorn snail and put it into the aquarium. My freshwater shrimps find crushed snails delicious, but Opae Ula ignored them completely. I make frozen food for my freshwater shrimps of following ingredients: boiled zucchini, carrots, green beans, spinach, green beans, raw saltwater fish, raw shrimp, chlorella and spirulina powder, vitamins.
I blend ingredients in a food processor, and then fix the pasty mass with agar-agar. Then I make mm thick flat packs in plastic bags, freeze them and store in freezer. My shrimps eat gram of this food for one feeding. This food was offered to Hawaiian shrimps, and they liked it.
After that they were positive to virtually any vegetable food that was fed to the rest of my shrimps: scalded spinach and Romaine Lettuce, cooked zucchini, cooked or canned green beans.
Boiled zucchini was initially inconvenient to use: slices of zucchini would not sink in salt water. This inconvenience disappeared over time as the number of shrimps in the tank reached hundreds.
They sat on the slice until it was sunk, and then it was completely covered with the mass of shrimps. So, I was offering to my shrimps a variety of food, but still kept feeding them with Chlorella and Spirulina powder as well: there were larvae floating in the water that were not able yet to pick food from surfaces in the aquarium.
I have observed the larvae for hours using special magnifying glasses. I saw enough to learn that for feeding larvae need a nutrient suspension in the water. Spirulina powder is optimal for this purpose: at sizes of micron particles of Spirulina were readily eaten by larvae. This suspension stays in the water for long time, and settled is immediately eaten by adult shrimps.
Watching how Hawaiian shrimps swim, I drew attention to the fact that they tuck up their legs, unlike other shrimps. I made the assumption that they developed this feature to reduce the water resistance, and thus, to save energy. On the contrary, they were very actively moving with the first two pairs of legs, those with claws. Suddenly I realized that these movements are actually the process of eating on Spirulina.
It turns out that even adult shrimps can eat food suspended in water. Now I feed Hawaiian shrimp with the same food as all the others. Their main food is zucchini, green beans and my home maid frozen food. In addition, one or two times a day, I add a pinch of powdered Spirulina to the aquariums. Despite the small size of adults mm , larvae of Hawaiian shrimps are quite large - about 3 mm in length. Female are berried for weeks, then larvae hatch.
The process of hatching is rather long and is easy to observe: a bunch of eggs becomes loose, and the hatched larvae continue to hang on my mother for a few hours before they go to float freely.
Also, in my opinion, the frequency of females becomes berried, and the number of eggs directly depends on keeping conditions and the quality of food. When I was feeding shrimps with small amounts of Spirulina, there were just berried females and larvae in the tank with shrimps.
This is easy to distinguish larvae of small shrimp: a larva hangs in the water head down and only occasionally jumps when it, for instance, is knocked by a shrimp. When the larva turns into a shrimp, its behavior is totally changed. Its movements become purposeful; it starts to swim head-first, using swimming pleopods. Keeping Hawaiian shrimp does not require special skills or special diligence. Salinity of the water in my tanks is grams of salt per liter of water SG 1,, I replace water from my tanks that I take for shipping shrimps, with fresh water of the same salinity, prepared beforehand in a separate tank.
Doing so, I use all aquarium volume every months. Shrimps are doing well. One must be prepared for the fact that in the aquarium with small number of shrimps and in which biological balance has not yet established, walls and other surfaces soon will be covered with a layer of algae. If this is very annoying, you can clean the front glass with aquarium scraper. If algae are developing very quickly, you can reduce the time of daylight to hours. When the number of shrimps grows, the cleaning becomes unnecessary: shrimps keep all surfaces of the aquarium in perfect condition.
They may be content with a small aquarium in an office, where they can easily stand daily fluctuations in temperature and no air conditioning at the weekend, the lack of food during the holidays and even the absence of the owner that left for a vacation or a business trip.
Hawaiian shrimps are cheerful and attractive in appearance. They can be kept in a small pot in the kitchen, instilling in kids interest and curiosity in aquatic inhabitants. A place to share my thoughts with other hobbyists.

Scientists announced today Jan. The announcement comes nearly two years after researchers aboard the British research vessel James Cook crowded around video monitors and became the first humans to glimpse an extraordinary sight 3 miles 5 kilometers below them, at the bottom of the Caribbean Sea: slender, rocky spires towering 20 feet 6 meters above the seafloor, spewing forth a sooty jet of metal-rich fluid some 3, feet 1, m high.
It was an overwhelming moment of marvel at our world," said marine biologist Jon Copley, with the University of Southampton in England. The revelations from the expedition, published today in the journal Nature Communications, come at an exciting time.
An expedition is at sea this week , aiming to take the first temperature measurements of the deep-sea vents, and take an even wider variety of samples. It's a site known as a mid-ocean ridge, where two tectonic plates are being wrested apart as fresh seafloor, extruded from the Earth's insides, is shoved between them. It's also one of the slowest, widening by just over half an inch 15 mm per year.
Following the discovery of the vents , Copley and his colleague Doug Connelly, a geochemist at the National Oceanography Center in Southampton, led an expedition that was the first to visit and take samples near the two undersea hot springs.
The shallower of the two vents, dubbed the Von Damm, lies 7, feet 2, m down, near the summit of an underwater mountain called Mount Dent. The second vent, the world's deepest at 16, feet 5, meters , is known by two different names, Beebe and Piccard, for William Beebe and Jacques Piccard, both pioneers of deep-sea exploration. Although the sites aren't far apart — just about 12 miles 20 km — the Beebe site is twice as deep, with twice the pressure, yet the team discovered the same species of shrimp living in both places.
The newfound shrimp, dubbed Rimicaris hybisae for HyBIS, the deep-diving vehicle used to fetch them, sport a light-sensing organ on their backs that resembles the angular robot-face logo of the evil Decepticons, the bad guys in the Transformers universe.
It's an appropriate feature for a creature with some remarkable shape-shifting adaptations of its own. Based on similar species seen at the Mid-Atlantic Ridge, Copley said, it appears likely that the shrimp begin life in the deep, but twilit, layers of the ocean, and have typical shrimp eyes, at the end of stalks. The young shrimp likely feed on a snow of decomposing material drifting down from the sunlit world above — "so they're feeding on photosynthetic-derived material," Copley said, a contrast from their chemosynthetic diet — one fueled by chemical reactions driven by the Earth's interior heat, instead of the sun — later in life.
Although their environment is pitch-black to human eyes, the hot vents emit an infrared glow. At their deep-sea homestead, the shrimp feed on gardens of bacteria they cultivate on their own bodies, a strategy also used by yeti crabs recently discovered at hydrothermal vents in the Antarctic. There was one big difference between the two shrimp populations, scientists said. In contrast to the pristine white creatures at the Von Damm site, the shrimp at the Beebe site were a grubby shade of orange, dyed by a fine dusting of rust.
Seawater samples show that the Beebe vent's fluid is extremely rich in metals — among them iron, which explains the rusty shrimp. When iron oxidizes it turns to rust. This hints at an alluring possibility, Connelly said. The vent might provide scientists with one of their first glimpses in the natural world of water in a supercritical-fluid state — water at such extreme high temperatures and under such high pressure that it starts to behave in weird ways.
It appears that supercritical water can act as a conduit for elements and valuable metals, preferentially stripping them from rocks and ferrying them from inside the Earth, "so there may be enriched mineral deposits around these sites," he said.
This type of natural strip-mining likely occurs deep inside other hydrothermal vent sites , but, once the fluid rises to a depth where the pressure diminishes, stops before the fluids come blasting out through the seafloor. At such depth, it could be that the pressure is so intense that the water retains its weird, mineral-mining properties in a place where — with great difficulty — humans can watch.
It could be "a window to what normally happens in the deeper sub-seafloor ," Connelly said. Another tantalizing indication that the Beebe site could be just such a window, Connelly said, came when the camera spied an unmistakable hue on the seafloor nearby — the bright, lustrous green of malachite , a precious mineral strewn generously about royal residences from Versailles to St.
Petersburg in forms as various as tables, urns and columns. Although he said that colors in the deep sea can be deceptive, and he has no way of knowing for sure until the substance is sampled, "to see that color green — it was very tantalizing. The discovery of the site, perched on a mountain top several miles away from the Mid-Cayman Rise's main volcanic activity, was a shock, and one with big implications.
A NOAA expedition found tube worms at the Von Damm site, a first for a hydrothermal vent site in the Atlantic, and yet another sign that animals travel among vent sites in mysterious ways. Connelly agreed, and said that, although the expedition was immensely informative, it also raised a lot of very big questions.
Some, such as the temperature of both the vents, will likely be answered in the coming days. Others will require years of research and further exploration. For him, Connelly said, being able to look but not touch much of the unexplored world he saw unfold before him in was exhilarating.

Swarms of a newly discovered species of shrimp cover a tower at the Beebe hydrothermal vent site, the deepest in the world. A black smoker vent at the Beebe Vent Field also called the Piccard Vent , the deepest in the world, and possibly the hottest. The newfound shrimp swarm a vent at the Von Damm vent site, alongside a pale, snake-like fish. The team also found a new species of snail and a new species of amphipod, a tiny crustacean, at this site.
