>>2503855The pic related you replied to is most likely a Japanese Spider Crab, another North Pacific species. The Pacific is the wild west of the worlds oceans and covers 1/3rd of the worlds total surface area. We have not even begun to understand or explore its full breadth in excess detail. An interesting feature of the subarctic/arctic and subantarctic/antarctic waters of the Pacific is that they are unusually rich in nutrients.
Another separate but random interesting fact, in the 70s a mild but good tasting orangish fish (Orange Roughy) was commercially fished off of Australia and New Zealand in the south Pacific, it was later determined that individual fish that people were eating had lived for up to 250 years and took a very long time to mature. More, living bacteria has been found in rock hundreds of feet below the seabed of the bottom of the ocean and sealife has been found under parts of the Antarctic ice sheets and unique bacteria has been found in isolated antarctic ice lakes.
