This lovely addition to the web site is by Jim Macaulay.

When Franklin Roosevelt was president, he kept exotic fish and other sea creatures in several aquariums in the White House. In one of those aquariums, he kept a moray eel. This was not just your average moray. In fact, it did not look like any moray you have ever seen. Some people referred to it as some kind of albino creature, but that was not completely accurate. This moray eel actually had transparent skin. Whenever it poked its head out from the rocks in the aquarium, Franklin and his guests could see beneath its skin.

This was such a novel attraction that, even today, people often talk about Franklin Roosevelt and his nude eel.
