Zebrafish microphotography

Updated: Oct 22

A stunning image of a zebrafish, used as a research animal model, has won Nikon's Small World microphotography competition.

Highlighted in numerous newspaper articles, including the UK Mail Online, the image was part of a groundbreaking discovery: zebrafish have lymphatic vessels inside their skull that were previously thought to occur only in mammals.

The discovery could advance research related to treatments for diseases that occur in the human brain, including cancer and Alzheimer’s.

“The image is beautiful, but also shows how powerful the zebrafish can be as a model for the development of lymphatic vessels,” said winner Daniel Castranova of National Institutes of Health, USA.
