Sammanfattning (abstract):
The skeletal remains of whale carcasses, or whale falls, on the sea floor harbours a highly specialised faunal community which in many respects mirrors the ecosystems found in association to deep sea hydrothermal vents on the mid-oceanic ridges. The community on whale falls is based on bacterial chemosynthesis of the energy rich lipids within the bones. On a sunken Minke whale in the Kosterfjord close to Tjärnö Marine Biological Laboratory in Sweden, representatives of whale fall endemic species was discovered within 10 months after the sinking of the whale. While all previously studied whale falls are from the Pacific Ocean, this is the first one known in the Atlantic. The whale carcass in the Kosterfjord is also unique in that it is placed on a relatively shallow depth of 125 meters. The studied whale falls in the Pacific are located at 1200 meters or deeper.
