I caught this image at the Texas State Aquarium down in Corpus Christi.  It's really a must-see if in Corpus and all the exhibits were really interesting.  We watched the dolphin show and then later found ourselves down below in their underwater viewing room.  It was crowded and hard to get a good shot as these creatures swam by, but I thought this one came out decently, all things considered.  Dolphins are interesting to watch and I love how they always seem to be smiling.  Friendly, ain't they?
