It has been observed recently that the plant-animal worm Symsagittifera roscoffensis exhibits circular milling behaviour, both in shallow pools at the beach and in Petri dishes in the laboratory.

Osedax is a genus of deep-sea siboglinid polychaetes, commonly called boneworms, zombie worms, or bone-eating worms. Osedax is Latin for "bone-eater". The name alludes to how the worms bore into the bones of whale carcasses to reach enclosed lipids , …

Nov 4, 2020 · It has been observed recently that the plant-animal worm $Symsagittifera~roscoffensis$ exhibits circular milling behaviour, both in shallow pools at the beach and in Petri dishes in the laboratory. Here we investigate this phenomenon, through experiment and theory, from a fluid dynamical viewpoint, focusing on the effect that an established ...

Circular milling, a stunning manifestation of collective motion, is found across the natural world, from fish shoals to army ants. It has been observed recen...

‘plant-animal worm’ (figure 1(a), Keeble 1910), engages in a photosymbiotic relationship (Bailly et al. 2014) with the marine alga Tetraselmis convolutae (Norris, Hori & Chihara 1980).

Feb 24, 2016 · Scientists have found that these worms self-assemble into structures that allow them to survive on broad, sandy beaches. One of the phases of this self-assembly is a big, floating worm spiral. The...

Vortex worms inhabit shallow marine waters and estuaries, typically found clinging to submerged surfaces like rocks, algae, or even seagrass. Imagine these tiny creatures, barely visible to the naked eye, navigating their watery world with graceful undulating movements.

Nov 4, 2020 · circular milling allows worms to self-organise into dense bio lms that, covered by a mucus layer, optimise the absorption of light by the algae for photosynthesis (Franks et al. 2016).
