The aquarium in Singapore has one of those cool walk-through tanks where you can get friendly with sharks.
But the best part was Gracie, the dugong. Dugongs are big underwater mammals like manatees. Supposedly they're the inspiration for the mermaid myth, but they don't look like a cross between a beautiful woman and a fish to me -- they look more like the front end of a pig welded to the back end of a whale. Here's a picture I swiped from the Australian Humane Society.
We kept getting on and off the moving sidewalk so we could ride by the dugong again. There was something captivating about her face, with its squashed nose, and the way her big bulbous body moved so gracefully through the water. Finally one of the keepers put a mat of seagrass in the tank. The dugong raced over and, before devouring it, did this funny cat-like thing of rubbing her face in it ecstatically. You could see the cartoon bubble over her head: Food! I love you, food!
Dugongs are endangered, of course. Sigh. We're going snorkeling this weekend, and it would be really cool to see one.
