It's a permitted question, mostly since experts have only just now found that these bizarre organisms may be remarkably more sprightly than anybody ever known. (Photo : Francesco Ungaro) The Numerous Trails of Sponge In a new study, scientists observed the deep Arctic seabed with an operated submersible that is far away, checking to locate signs of life beneath the ocean at the top of the world. Across the seamount peaks of Langseth Ridge submerged in the Arctic Ocean, they discovered something they never anticipated - spong...

Sponges: They are considered to be one of the most primitive forms of animal life, because they have neither locomotion organs nor a nervous system. A team around deep-sea scientist Antje Boetius has now discovered that sponges leave trails on the sea floor in the Arctic deep sea. They conclude that the animals might move actively - even if only a few centimetres per year. They are now publishing these unique findings in the journal Current Biology. The surprise was great when researchers looked at high-resolution images of the sea floor of the Arctic deep sea in detail: Path-like tracks acr...
