Red Lionfish on the Reef — Underwater Postcard

Long white spines fan out like a crown around this red-striped lionfish, caught mid-display against a rocky coral reef. The close-up framing captures every translucent ray and the fish's sharp, watchful eye. A vivid card for anyone drawn to reef life and underwater photography — tuck it into a letter to a diver friend, or start a marine-themed postcrossing swap.
