Nice photos! I really like the ornate ghost pipefish photos as they're such weird critters.
Our publisher has some macro HiDef video footage of pygmy seahorses.....you still photogs are lucky, just try keeping a huge HiDef videocam with humongous HID lights perfectly still on a pygmy seahorse in a strong current with surge all the while fully zoomed in and with a +2 diopter macro lens in place.
And do this while not mnaking the viewer who is sitting perfectly sitll on the couch get seasick.
