Rare Shark Filmed in Japan

[TheBORG] writes "A Deep Sea Frill Shark, whose normal habitat is between 600 and 1000m, was found and filmed off the coast of Japan recently. Normally they're caught (found dead) in fishermen's nets. This 'living fossil' was probably so close to the coast because it was sick. In its poor condition, the shark was moved by marine park personnel to a seawater pool where they filmed it swimming and opening its jaws. The shark died a few hours later after being filmed."

    Correct me if I am wrong but humans can go a bit deeper than 1000 feet as mentioned in the article.

    http://www.ussubs.com/faq/luxury.php3 a small deep submersible could be carried "piggy back" by the Seattle, allowing a small group of 2-3 people to board the deep submersible through a transfer lock and dive to depths of up to 3000 meters or more.

      7. How deep can the submarine dive?

      The Seattle 1000 is designed to dive to 305 meters, or 1000 feet. This is an optimum compromise that allows exploration at significant depth but also allows us to have very large viewports for exceptional visibility. If necessary, a small deep submersible could be carried "piggy back" by the Seattle, allowing a small group of 2-3 people to board the deep submersible through a transfer lock and dive to depths of up to 3000 meters or more.

      They mean humans with SCUBA equipment subjecting themselves to extreme ambient pressures -- not diving in submarines. Deepsea submarines have taken man to the very deepest parts of the oceans (about 11,000m), but the record for technical diving with special SCUBA equipment is 318.25m: a record set by South African Nuno Gomes in Dahab (Sinai, Egypt) in 2005. Such dives are very dangerous and require careful management of multiple gas mixtures composed of oxygen, nitrogen and helium (trimix) to prevent problems like nitrogen narcosis, oxygen poisoning and decompression sickness (the bends). Deep dives like this also last so long (Nuno's dive was over 12 hours) that lots of other problems, such as hypothermia and dehydration, have plenty of time to develop.

      The deepest simulated dive is 685.5msw (meters of sea water) set at Duke Medical Center (Durham, North Carolina) by three divers in 1981. In cases like this, HPNS (high pressure nervous syndrome) is the limiting factor. HPNS is a syndrome of neurologic dysfunction with symptoms that include tremors, dizziness, vertigo, nausea, visual distortions and altered sleep. Tremors associated with HPNS have been reported as shallow as 128.72msw, but the deeper you go, the more likely HPNS is to occur. Eventually, it can prevent a diver from performing essential tasks during a dive.

      Knowing this, you have to admire those sperm whales: mammals that are believed to be able to dive as deep as 3,000 metres and then go hunting for food at that depth!

    I don't understand why a shark would surface if it was sick, that would just make it more vulnerable to unforeseen predators.

    This is quite common in *many* animal species. Even dogs and raccoons do this. Obviously, when a creature gets physically sick (or old), often they are also mentally deficient as well, just like humans. With animals, however, they often wander into strange places, away from others of their kind, and generally do things they wouldn't ever normally do. This can be attributed to loss of sensory capabilities, perception, and many other things.

    In some ways, this is advantageous -- not to the individual creature, but to the overall population -- and can potentially be considered advantageous behavior. If a creature is infested with a disease, the further away it gets from its healthy kin, the better off they are likely to be. If the creature is just old, it can benefit the rest of the 'pack' by leading predators away, at very least, before it dies.

    Back on topic... This thing looked pretty beaten up. Granted, I haven't ever seen one before, but it looks to me pretty old and out of it. It was just its time -- I wouldn't attribute its death to anything else unless you start seeing many more similar cases. Then it makes sense to worry. Until then, this is just kind of 'cool' for us monkeys.

    One of the first symptoms of many types of sickness in most species of fish is difficulty controlling their buoyancy. If you have a fish tank and your fish is sitting at the top or bottom of the tank and moving slowly, that's a good sign it's a sick fishy.

    Interesting, in the video it looks like it is keeping its gills crazy-open none-stop. It looks like its desperately trying to get enough water across its gills. Maybe it just died of exhaustion because of the effort? Kind of like what people go through when not used to mountain atmospheres and get out of breath fast.

    My free guess: it almost got caught by a fishing net which wounded it. The damage caused the fish to become disoriented. Lack of oxygen further disoriented it and all it could to stay alive was try to get more water across its gills. Eventually it died from exhaustion.
