These strange-looking creatures may look like ear-less teddy bears with tails – but this micrograph is actually two-day-old zebrafish larvae, as seen through a scanning electron microscope. The image was captured by Jurgen Berger and Mahendra Sonawane, both employees at the Max Planck Institute for Developmental Biology.

The zebrafish, or Danio rerio, is a common tropical fresh-water fish. Within three months, the larva turns into an adult (the two holes above the mouth in the picture above show not its eyes but a developing olfactory system.) During the larval stage, the zebrafish has the ability to regenerate fins, skin, heart and brain. Learn more about this fascinating critter here: zebrafish.org
