In what probably stemmed from a drunken bet, scientists in Turkey have created rabbits that glow in the dark.
They did it by inserting a gene from a jellyfish into the rabbit genome using a process called transgenesis.
The jellyfish protein is linked with emission of a bright green glow when put under ultraviolet light.
Though the process is said to be harmless, the jelly-bunnies will pass down this mutant property to their offspring.
Scientists at the University of Istanbul were able to make two of the litter of eight rabbits glow green.
The goal is to learn how to make livestock a kind of living laboratory for proteins used in medications.
One researcher said, according to the Los Angeles Times:
"Animals can make valuable proteins in their milk that humans use for medicine, and you can extract the proteins quite easily.
"It would make certain pharmaceutical production extremely cost-effective."
