No, this ghostly gator isn't one of those sewer-crawling descendants of something someone's brother once bought off the back of a comic book (still, look before you sit!).

It's one half of a pair of rare albino alligators unveiled yesterday at their new home in a French aquarium, bought from a reptile collector in Florida. (Cost? More than 40,000 euros โ€” each.)

The gators, which are more than a year old and look to be 2 or 3 feet long, are two of no more than 30 in the world. Blame recessive genes for their bright, white skin that burns in the sun and quickly attracts hungry predators โ€” or fans.
