Photo of the Day ~ Sea Pens

Soft corals known as sea pens, usually found at depth, and a blue cod appear in the shallow waters of New Zealand's Long Sound reserve, where tannin-stained water blocks light. When disturbed, sea pens emit a greenish light and can deflate, retreating into their bulbous feet.
