1) Computers.  I'm a gadget person and a data person, I like to look at the numbers and graphs.
2) Blennies. I can't tell them apart, but I love the way they keep popping in and out of their holes.
3) Sea Anemones. They're always so relaxed, just waving in the breeze. And they almost always have little friends with them!
4) So many! But one I'll always go back to, because it's easy to get to, relaxed, has huge biodiversity, and available at day or night, I'd say my favorite is the Blue Heron Bridge in West Palm.
