http://news.bbc.co.uk/cbbcnews/hi/newsi … 071039.stmScientists have bred a group of marmosets that glow when they are exposed to ultra-violet light.
They did it by altering the monkeys' genes. Genes are the basic building blocks of life, almost like a set of instructions for a living thing.
The achievement is important because one of the marmosets had a baby which also glows - the first time something like this has happened with monkeys.

It may seem like a fun little thing to do but if you are going to play around with animal genes at least make it useful to the animal rather then make them glow in the dark play things.
