Woodhouse Reef

The four reefs of the Strait of Tiran, Jackson, Woodhouse, Thomas and Gordon, are named after 19th-century English cartographers. Woodhouse is a long, narrow reef of about 0.8 miles, and on the northern half of its eastern side a canyon opens and runs parallel to the reef, with a red anemone marking the exit. On the saddle between Woodhouse and Jackson, in choppy seas, the water turns over and forms a powerful eddy that local divers call the "washing machine".

The reef is very colourful, with plenty of hard and soft corals and colonies of Antipathes black coral, alongside the spiral Cirrhipathes. Jackfish, tuna and turtles also appear on the reef.
