Italiano: A sinistra: biocostruzioni ad opera di solfobatteri in una grotta sulfurea alla profondità di circa 30 m a Santa Cesarea Terme (LE).
A destra: le stesse biocostruzioni in sospensione in acqua.
Tali strutture sono estremamente fragili, anche una piccola bolla d'aria emessa da un subacqueo può disperderle in acqua.
English: On the left: Bioconstructions created by sulfur bacteria in a sulfurous cave at a depth of about 30 mt in Santa Cesarea Terme (Lecce), Italy. On the right: The same bioconstructions suspended in water. These structures are extremely fragile, and even a small air bubble emitted by a diver can disperse them in the water.
