These folds can be wide or narrow, prominent or subtle. These features of the columella are often useful in identifying the family, genus, or species of the gastropod. The surface of the columella is called the columellar wall. The columellar callus is a smooth, calcareous thickening, secreted by the mantle, extending over the columellar area ...
Some of the Bifidobacterium animalis bacteria found in a sample of Activia yogurt: The numbered ticks on the scale are 10 micrometres apart.. In 1899, Henri Tissier, a French pediatrician at the Pasteur Institute in Paris, isolated a bacterium characterised by a Y-shaped morphology ("bifid") in the intestinal microbiota of breast-fed infants and named it "bifidus".

It is expanded and deeply sinuated in front, with the outer margin disunited at the suture. The columella is exposed, revealing the inner whorls. The color of the shell is muted, ranging from pale brown to greenish hues. The head-disc is greatly elongated, wide, and bifid anteriorly, tapering towards the rear.
