A Nautilus shellfish appears to be Aquascaping its tank in Washington DC.
This creature was apparently one of the first animals to begin its existence on the planet and could possibly be the last except perhaps for a few cockroaches. Yet there appear to be few videos of its habits and habitat on the intertubes.
Nevertheless this most fundamental self sustaining life form on the planet continues to inspire us.
