    Although sponges are an aquatic animal, people usually think that they are completely fixed: once settled in a place and matured, they will not move.


    "We observed that the tightly intertwined needle-like traces are directly connected to the underside of the individual sponge, indicating that these traces are traces of sponge activity.


    These traces look like sponges "climbing" to their current position.


    Nevertheless, the new findings surprised the researchers.


    Data obtained from a towed marine camera sled and a hybrid remote-controlled vehicle show that the peaks of the Lances Ridge are covered with one of the densest sponge communities in history, the main species being Geodia parva, G.


    They said that considering the challenging environment, it is unclear how the area supports such a large sponge community.


    These marks are several centimeters high and several meters long.


    Researchers generated 3D models based on images and videos to show how these trajectories interweave.


    The researchers wrote: "These characteristics indicate the behavioral trends of feeding and population density previously observed on sponge shells.


    This movement may also be related to reproduction or the spread of young sponges.
