Taiwan Scientists Breed Green-glowing Pigs.

From the website:

The pigs are transgenic, created by adding genetic material from jellyfish into a normal pig embryo. [...]

Taiwan is not claiming a world first. Others have bred partially fluorescent pigs before; but the researchers insist the three pigs they have produced are better. [...]

In daylight, the researchers say the pigs’ eyes, teeth and trotters look green. Their skin has a greenish tinge.

In the dark, shine a blue light on them and they glow torch-light bright.

The scientists will use the transgenic pigs to study human disease. Because the pig’s genetic material encodes a protein that shows up as green, it is easy to spot.
