Dolphins more intelligent than store employees?

I seem to be doing a lot of linkblogging today.

Note to self: should set up some sort of system that does this sort of thing automatically from del.icio.us or somesuch.

The latest link comes from Jeremy Zawodny who writes about some very clever dolphins:

Kelly has taken this task one step further. When people drop paper into the water she hides it under a rock at the bottom of the pool. The next time a trainer passes, she goes down to the rock and tears off a piece of paper to give to the trainer. After a fish reward, she goes back down, tears off another piece of paper, gets another fish, and so on. This behaviour is interesting because it shows that Kelly has a sense of the future and delays gratification. She has realised that a big piece of paper gets the same reward as a small piece and so delivers only small pieces to keep the extra food coming. She has, in effect, trained the humans.

and some very dumb workers:

So then I opened my mouth and said something like “you have a list with 8 items on it and I have 9 items. This shouldn’t be rocket surgery.” She put the clipboard down and I started to think she realized how crazy this all was. But what happened next only served to amaze me even more! She called a co-worker over to help.
