Biological and abiotic tubes. SEM images of tubular colonies of a) Aspergillus niger feeding on straw (image: Anna Neubeck) and b) manganese oxide chemical gardens (image: Huld et al., 2023). The A. niger tubes ranged in size between 2-5 µm in diameter, and the manganese oxides were found in ranges between 1–20 µm in size.
