Examples of transgenic animals:

Gold Seahorse

Scientists at Vietnam's National University's College of Science combined light emitting genes of jellyfish with grains of gold and injected the combinations into the seahorse egg cells. The results was seahorses with sparkling gold on the body.

Umbuku Lizard

Genetic Engineers in Rhodesia managed to unlock a dormant “flying” strand in the DNA of the Umbuku lizard, a very small and rare lizard native to Africa. It is believed that the lizard is a descendent of the Pterodactyl, which lost its ability to fly some millions of years ago. To date only 6 of these flying Umbuku have been produced and they are kept seperate from the natural Umbuku due the risk of cross breeding.

Dilion

A Dilion is a cross-breed between a lion and a dog.
In order to produce these animals individual DNA from each creature must be combined and re-inserted in to a host egg. This is similar to a liger with the exception that the liger is able to be produced without prior manipulation of the DNA of either breed of animal.
