HALLOWEEN PICTURES: Spooky Species Discovered This Year

October 29, 2009--While he may not vant to suck your blood, this male fish does sport spooky-looking fangs that have earned it the name Danionella dracula—and that's more than enough to qualify as a one of the spookiest new species announced in 2009.

The fangs of D. dracula--discovered in March 2009 in Myanmar (Burma)--aren't actually true teeth. The line of fish that gave rise to the ghoulish species is thought to have lost teeth for good around 50 million years ago.

Instead, researchers think the males use these extralong fangs to spar with each other during aggressive displays.
