Abstract
Sexually active males of the family Blenniidae develop distinctive glandular swellings of the anal fins. These glands can be divided into four groups on the basis of their shape and whether they appear on the anal fin spines or rays or both. Examples of each group, when studied microscopically, show the same histological pattern. This pattern includes three layers of tissue, the outermost of which contains characteristic barrel-shaped groupings of cells called "microglands". These anal fin glands are compared histologically to similar structures on the dorsal fins of some blenniids and the anal fins of certain clinids. The microscopic structure of the anal fin glands is distinctive and characteristic.
