its one thing to try to capture some little bitty fish zipping in between coral, and another to chase down two giant spotted eagle rays at 120 feet below when half your dive party hasn't even decended yet and at that depth chasing big fish this fast uses a lot of your oxygen. i never got as close as i of course wished i could have, but it was stunning to spend the minute or so seeing them swim, play, and otherwise just 'be' in a world that humans don't quite fit in to.
