It all started in the 1950s in Kyoto, Japan, where an inventor discovered (or utilized
somebody else's discovery) that by putting certain types of "sugar" compounds of monosaccharide's and polysaccharides
together, fresh water could be modified to maintain successfully both fresh and saltwater fishes in the same water
environment. It was an incredible invention that was offered to Kordon to bring to the U.S. aquarium market. Once
Kordon found that it indeed worked, it was called "Wonder Water." Kordon started experimentation on the product and
trial distribution of the product to advanced experts in aquarium keeping and through wholesale distributors to advanced
aquarium stores -- mainly on the U.S. west coast. Click
An Australian swimmer survived a great white shark attack by poking the creature in the eyes
as it dragged him through the water after badly savaging his left leg. Jason Cull was swimming off a beach on
Australia's southwest coast on Sunday when the four meter (12 feet) shark attacked. "Initially I thought it was a
dolphin," Cull told The Australian newspaper on Monday. "I just remember being dragged along backwards. I was trying to
feel its gills but I found its eye and I stuck my finger in and that's when it let go." The shark tore two chunks from
Cull's left leg, ripping off half his calf and leaving him with deep lacerations to his knee and thigh. A local surf
lifesaver heard Cull, 37, screaming and raced into the surf to rescue him. Click
Arguably the oddest beast in Nature's menagerie, the platypus looks as if were assembled
from spare parts left over after the animal kingdom was otherwise complete. Now scientists know why. According to a
study released Wednesday, the egg-laying critter is a genetic potpourri -- part bird, part reptile and part lactating
mammal. The task of laying bare the platypus genome of 2.2 billion base pairs spread across 18,500 genes has taken
several years, but will do far more than satisfy the curiosity of just biologists, say the researchers. "The platypus
genome is extremely important, because it is the missing link in our understanding of how we and other mammals first
evolved," explained Oxford University's Chris Ponting, one of the study's architects. "This is our ticket back in time
to when all mammals laid eggs while suckling their young on milk." Native to eastern Australia and Tasmania, the
semi-aquatic platypus is thought to have split off from a common ancestor shared with humans approximately 170 million
years ago. Click
That is the fascinating conclusion of the latest research into fish behavior by researchers
from the ARC Centre of Excellence for Coral Reef Studies and James Cook University, described in the journal Current
Biology. The same team who recently revealed fish use the threat of punishment to keep competitors in the mating game in
line, have taken the work a step further to discover that subordinate fish deliberately go on a diet to avoid posing a
challenge to their larger rivals. “In studying gobies we noticed that only the largest two individuals, a male and
female, had mating rights within the group,” explains Dr Marian Wong. “All other group members are non-breeding females,
each being consistently 5-10 per cent smaller than its next largest rival. We wanted to find out how they maintain this
precise size separation.” Click
The rare Barrens Topminnow, a tiny fish unique to Middle Tennessee, is getting a shot at
survival without going on the Endangered Species list. Instead, the fish, which tops out at only four inches in length,
is part of a pilot restoration project based on cooperation rather than severe legal restrictions. "We looked at ways to
save the fish without having 'big government' come in,'" said Matt Hamilton, senior aquarist at the Tennessee Aquarium
in Chattanooga. The minnows were in streams crossing the land of less than a half dozen property owners, Hamilton said,
which made it easier to devise a cooperative project with state and federal and private agencies. Several landowners
have been willing to fence cattle out of the creeks or make other accommodations to protect the water. Margaret and
Steve Cunningham of Manchester are among about two dozen landowners who have allowed release of the minnows in a creek
on their property. Click
The blue shadows of sharks circled ominously round and round the child. Then the toddler
reached out and banged her hand on the glass. Her dad smiled. On another recent day, the doctors at a local trauma
center asked, "How the hell did you get bitten by a shark in Kitai-Gorod?," when a staff member from the Sea Aquarium at
Chistiye Prudy came in, bleeding from bite wounds on his arm. "They thought he was drunk," said Mikhail Berezin, the
director and founder of the aquarium. The aquarium, which is the only one of its kind in Moscow, began as a one-room
fish store in the basement of the art deco building near the pond at Chistiye Prudy in 1998. Since then, it has grown
into a very popular, four-room weekend institution for families, experts and hobbyists alike. "I don't advertise,
because then there would be traffic jams up and down the Boulevard Ring," Berezin said. If the crowds packing his venue
are any indication, this is not an idle boast. "This is our first visit, but we're really glad we came," said a woman
carrying her grandson past a display of bright red-and-white-spotted crystal red shrimp. Click
The giant squid is real, but stories of sperm whales wielding blasts of sound to impair them
may be nothing more than a fairy tale. Scientists have long known that giant squid are a major source of food for the
even larger sperm whales, which have been found beached with sucker-mark battle scars across their skin and monster-like
tentacles in their stomachs. Regardless, how these giant whales snag their various forms of nimble prey has puzzled
biologists for decades. Sperm whales have the world’s largest biological sound machine housed within their 10-ton heads.
The idea of the “acoustic prey debilitation hypothesis” (also more charmingly called the “Big Bang Theory”) was first
mentioned in a science magazine in 1963. The word “debilitation” is appropriately vague. The sheer power of a sound wave
can cause physical damage, like hemorrhaging. Or a sound could possibly confuse or disorient prey instead. Click
U.S. researchers say they have developed a technique to kill harmful marine life that
hitches a ride on cargo ships from other parts of the world. The invasive species found in ballast tanks, which are used
to steady ships as they load and unload cargo, could be eliminated by microwave emitters fitted to the exit valves on
the tanks, according to researchers from Louisiana State University's Agricultural Center, whose work will appear in the
journal Environmental Science and Technology. The microwaves would generate enough heat to kill the organisms living in
the ballast water, which the United Nations lists as one of the four main threats to the world's marine ecosystems.
Large cargo ships usually have internal tanks that draw in water when cargo is being unloaded in order to avoid
capsizing. The tanks are pumped out when the ship is reloaded, often after the ship has traveled to a different part of
the world. As a result, species from one part of the world hitch a ride to waters in a different part, where they can
harm the native marine life. Click
