While adult sponges can and do slowly change their position in response to different external stimuli, they're not exactly well-known for their agility or speed. "This is the first time numerous sponge trails have been seen in situ and related to sponge mobility," the team, headed by Teresa Morganti, a marine biologist from the Max Planck Institute of Marine Microbiology in Germany, describes in a new paper. Biologists have for long regarded sponges as largely sessile form of life that hardly ever move, except they are in their larval stage.Īlso Read: Sea Sponge: The Strongest 'Uncrushable' Glass Skeleton Species Sponge's Locomotion Across the seamount peaks of Langseth Ridge submerged in the Arctic Ocean, they discovered something they never anticipated - sponge tracks, strange trails evidently left behind by some closeby and otherwise very-stationary-appearing sea sponges. 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.
