One remarkable characteristic of the girdle structure is its capacity to exhibit two easily distinguishable rows of pores within the striae when viewed under a light microscope. This unique trait sets it apart as there is no central gap present, and the number of fibulae (rod-like structures) and interstriae (spaces between the fibulae) is roughly equal. This specific arrangement within the girdle structure is a notable feature, enabling it to be readily identified and differentiated from other diatom structures. This clear distinction aids in the accurate classification of diatoms and contributes to a better understanding of their morphology and characteristics.
