Lecture from LFS

[Delphinus]

I'd say he pretty much invalidated his position when he said he hasn't fed his fish in years.

But anyhow, for what it's worth, I'm no world-class diver by any stretch, but I did dive and snorkel in the Great Barrier Reef in 2001, and I remember vividly that the water temperature was 26 (which converts to 79F). And this was considered "cold" for most of the Aussies on the boat with us. The 2 Canadians (my wife & I) were the only fools who went into the water without wetsuits. (I mean, come on, 26C? The water in BC is, what, maybe 12C? Maybe 15C? And people swim in it all the time. Compared to that the GBR was like swimming in bathtub warm water!)

But Drew is right: temperatures fluctuate not only with geographic regions, but with depth and .. well heck ever stick your finger in a tidepool at high noon? And things live through that.
