Puff, the Magic Genome: ‘After nearly a decade of hard work, researchers are close to paydirt. They’ve got the genetic sequencing of the Japanese pufferfish about 90 percent complete.

Why all this fuss over such an odd little fish?

Well, it turns out that the pufferfish genome is remarkably similar to the human one, making it a valuable road map for human geneticists. Not only that, but it doesn’t contain all the “junk” found in human DNA, the stuff that makes finding actual genes so difficult.’ Wired
