I've read that these monsters' spawns are completely random, but I know that at least some of the types have a proclivity for a certain area. (E.g., pink boroks in first valley of Adorton Station, albino skags with Claptrap's urine quest.) They aren't listed in the wiki. Where are the best places to find each of these?
It is the same symbol that was all over Borderlands 1, and is still the 'saving' icon in Borderlands 2.
As you explorer them, you will find some small (like this screenshot), some large, some half obscured by objects, some on floors, some on walls, etc.

Well it turns out they aren't in the "breakable" goo piles but actually suspended in the solid "drips" of stalker goo. You have to "collect" them with Pick Up/Action for them to count. This video has the locations:
Note this is another challenge you may as well do solo, only one person can grab any individual bear and they don't count for everyone.
Best Answer
As far as I know, there are no specific factors that influence rare creature spawning, so the answer is just "anywhere lots of base creatures spawn". Here's a list of creatures' affinities to areas of Aegrus:
Suggested farming areas would then be: Hunter's Grotto for spores, drifters, and boroks, Candlerakk's Crag for scaylions, and Scylla's Grove for skags. If farming for boroks, it may be effective to start at the Lodge, run through Scylla's Grove to Ardorton, reload there and head back.
