Ooooh a Delicacy.
This little SOB the 'candiru' needs to become extinct as soon as possible.
It is definitely a parasite, it produces nothing of value, it needs to be eradicated from the planet.
On the other hand, perhaps a few dozen of the little beasties could be dropped into the 'Al Franken for Senate Pool Party' for this coming summer in Minneapolis.
OK, maybe they can serve a useful purpose. ;)
