Glowing Green Jelly-Monkeys

Seriously:

Japanese researchers have genetically engineered monkeys whose hair roots, skin and blood glow green under a special light, and who have passed on their traits to their offspring, the first time this has been achieved in a primate.

They spliced a jellyfish gene into common marmosets...

At least the wicked witch created flying monkeys. Useful, are flying monkeys. They can track down annoyingly cute stray farm girls. But jelly-monkeys?

What's that? Medical research. Oh, suuuure... It's always "for research purposes," isn't it? Grant denied. Go back to the drawing board... and think "wings" this time.
