Tricky Mammals

I liked this NYT article by Natalie Angier about deceitful animals, particularly the part about deceitful dolphins.

One safe generalization seems to be that humans are real suckers. After dolphin trainers at the Institute for Marine Mammals Studies in Mississippi had taught the dolphins to clean the pools of trash by rewarding the mammals with a fish for every haul they brought in, one female dolphin figured out how to hide trash under a rock at the bottom of the pool and bring it up to the trainers one small piece at a time.

Now, if dolphins could only take up wearing top hats and carrying magic wands, maybe they'd have a career in show business.
