This soldier crab is "collecting" a diatom bloom in salt foam, and wraping it around  his body. He then carries this some distance and  buries in the mudflat (presumably as a future food store). Watching thousands of these bubble encrusted crabs meandering across the mudflats is an amazing sight,  but it only occurs under unusual conditions, there needs to be an algal bloom of the diatoms with enough wind to whip some salt foam and blow this salty algal dinner onto the shore.
