For a small, ocean-loving subset of visitors, this dusty corner of the Middle East is renowned for more than political turmoil. Every year, from February to May, the coral reef off Eilat's coast is an unparalleled place to spot some of the planet's strangest, most beautiful animals: nudibranchs, or tiny, jewel-like sea slugs. While the words "sea slug" probably don't ignite your imagination like "great white shark" or "blue whale," there may not be more spectacular critters in the entire ocean.
