Recently, researchers at the Victoria Museum in Australia have obtained a very rare specimen of the scorpion shark. A few weeks ago, a trawler accidentally captured a giant basking shark in the Bass Strait in southeastern Australia. The basking shark is 20 feet long and weighs 7716 pounds, which is very rare. In fact, this is the first scorpion shark that has been captured in this area since 1930. It is also the third basking shark that has been caught since 1855. Unfortunately, this basking shark has died when it was caught. . The basking shark is highly sought after because its fins can be made into shark fins. But the fishermen who captured the giant fish felt that the scientific value of such a rare big fish should have been higher than the economic value, so they decided to donate the shark to the Victoria Museum for research purposes. After receiving the scorpion shark and the second largest fish after the whale shark, the Victoria Museum decided to preserve it forever with advanced 3D scanning and 3D printing technology . “This is the first time we have done a 3D scan in this museum, especially for such a large object,†said Martin Gomon, senior curator of fishology at the museum. “We can compare its morphology to fish from other regions to see if it belongs to a different species, or how it relates to other species. And we can also check its internal structure by X-ray or CAT scan. So it is very valuable." Because the fish's body is too large, the researchers decided to remove its largest dorsal, anal, pectoral, pelvic and some of its vertebrae, and only 3D scan the head and ankle. They used a handheld 3D scanner operated by Ben Tam, an engineer from scanning company Qubic. Tam's 3D scanner can cover an object of one meter every 4 seconds, and can capture 10-15 frames per second. Once the highest precision of the entire head, mouth and jaw has been scanned and captured, the museum will copy the head of the basking shark through 3D printing and display it publicly. Let people observe this rare giant shark at close range.
There are many kinds of Glass Door Locks, but mainly two
types which for glass cutting and no need glass cutting. The
advantage of the glass lock is that the glass doesn't need to cut-out and also
can keep safe better. So glass lock is more and more popular. And we JIANGYI
company is specialized in manufacturing all kinds of glass hardware for more
than 20 years. We persist to develop new models and use good materials to cope
with the increasing variety need of domestic and foreign markets.
