Ornate (also called "Harlequin") ghost pipefish in a crinoid. Note that because red is not generally visible to other sea creatures (red light waves are absorbed in the first 15 feet of water), his red coloration would not make him "stand out" like this against the blue crinoid. We see his true color because of the strobe on my camera, which sheds the full spectrum of light on him.
Pygmy seahorse (approx. 1/2 inch tall) - the tiniest type of seahorse/pipefish. Note how its body color and texture mimic the coral on which it lives!
Frogfish (the common name) are actually "anglerfish" - so named because they all have little "lures" on their forehead that can be waved in front of them to attract small fish, which they then gulp down. Generally mimicking big lumps of something - most often sponges - they are quite sedentary...sort of the "Jaba the Huts" of the underwater world. And frankly, they're so ugly they're cute!
