Microphotography as Art Confocal image (extended focus Z stack)

Embryo of the dwarf cuttlefish Sepia bandensis Stained with phalloidin (F-actin; green), DAPI (nuclei, blue), and anti Pax 3/7 (MAb DP312, red).

The developing cuttlebone (purple) and eyes (yellow) were rendered using the DIC image collected during the confocal scan. The F-actin staining (green) reveals the developing musculature and brain, while Pax 3/7 (red) is expressed in a subset of neurons in the brain as well as two patches of epithelia in the mantle and portions of the arms and tentacles.

The cuttlebone (purple) is a chambered, gas-filled internal shell made of aragonite that provides buoyancy control. Within each eye (yellow), the developing lens is seen as an internal sphere.

Seven of the eight arms are visible along with the two tentacles that have sucker-covered ends.

Chicken Embryo

10-day-old chicken embryo in a test tube, part of Hans Larsson's study at McGill University. His study involving manipulating embryonic development and turning the chickens into dinosaurs.

Yes, it was based off the Jurassic Park idea. But Larsson said, "It's a demonstration of evolution. If I can demonstrate clearly that the potential for dinosaur anatomical development exists in birds, then it again proves that birds are direct descendants of dinosaurs."

Bat Embryos

The first image are embryos of the species Molossus rufus, the black mastiff bat. These images formed part of an embryonic staging system for this species. -- By Dorit Hockman

The second image shows a bat embryo developing from 18 weeks to 24

The concept of an embryo is a staggering one, and forming an embryo is the hardest thing you will ever do. To become an Embryo, you had to build yourself from a single cell. You had to respire before you had lungs, digest before you had a gut, build bones when you were pulpy, and form orderly arrays of neurons before you knew how to think. One of the critical differences between you and a machine is that a machine is never required to function until after it is built. Every animal has to function even as it builds itself.
