Photomicrographer James E. Hayden, RBP has been a consistent winner of the Small World competition for many years. Featured below is a photomicrograph of a zebrafish specimen taken with darkfield illumination.

Danio rerio (Zebrafish) Gill Branches Original Magnification: 39x Specimen: Hematoxylin and Eosin Section Technique: Darkfield Illumination

Enlarged further from the Danio rerio (Zebrafish) Gills image, this image of tangentially sectioned gill branches in the zebrafish reminds the viewer of a row of termites, or other insect converging on an object. From a scientific point of view, the color differentiation in the section caused by using the darkfield technique provides a wonderful illustration of the structure and composition of the gill branches. Either way, it adds even more to the story already begun with the Zebrafish head and Zebrafish gills images.
