They use their foot to agitate the water’s area, generating bubbles, which they bind together with mucus. This mucous-bubble mixture hardens to kind a floating raft, which the snail attaches alone to. If it gets to be partly detached from its raft, the storm snail quickly creates new bubbles with its foot by extending it in direction of the surface, swiftly folding it to encase an air bubble, and coating the air bubble in mucus secreted within the propodium (anterior Portion of the foot). Creating a mucous-bubble will take roughly ten seconds and the snail can make about 10 within a row just before pausing.
“Once i saw it within the Seaside, I quickly understood what it had been, but I was in total shock,” mentioned Stajner, a fifth-yr doctoral college student on the Scripps Institution of Oceanography at UC San Diego. “I would by no means anticipate to determine one washed up in San Diego.
