The middle pic is a tuxedo urchin.  They like to pick up stuff and 'camoflage' themselves.  It's been carrying this little strip of star polyps around for about 3 weeks.  Doesn't seem to bother the polyps at all.  Looks like an easter bonnet to me.   :smile: 
Thanks for the compliment.  I just really started playing around with all the manual settings, and I'm enjoying it.  The camera is an olympus 5050.  I got it about a year ago.  Overall it's a great camera to learn stuff on, however if I was going to get one today it'd be the olympus 8080.  It's less than what I paid for the 5050 a year ago, it's 8mp instead of 5mp, and they use the same lenses for it that are used in the digital SLR cameras, by all reports/reviews it's VERY slick.
