Cry havoc...
...and let slip the dolphins of war.
For context: I'm Canadian.
Last week, my co-workers and I were discussing the US Navy's use of trained dolphins to find underwater mines. (National Geographic | Globe and Mail) The dolphins swim around, find the mines, and mark them with floats. Apparently, the Navy has been training dolphins and other marine mammals -- sea lions, beluga whales, killer whales -- for 30 or 40 years. (I read a couple different figures.)
Our first reaction to this was quite negative: oh, the poor dolphins, how can they do this? It's not right, etc. Then someone raised the question of dogs, working in similar situations. That didn't bother us much at all.
( So, now I wonder why... )
