PHOTOGRAPHY BY ALAN SUTTON

Nudi city is a scuba dive site in the channel between Mafia Island and Chole Island.  The name nudi city is a reference to the unusually large number of nudibranchs in the area. Eight different species of nudibranchs and flatworms in one dive is a pretty good score sheet. The dive starts out from the beach in front of Mafia Island Lodge and the maximum depth is 11 meters so it is possible to do a fairly long dive.

The dive, best dived at night is across a sandy bottom with scattered bits of hard and soft corals and isolated bits of seagrass. Various species of nocturnal fish such as lionfish, scorpionfish, arabian monocle breams, cardinals, blue spotted rays and bigeyes can be seen out hunting. Sea pens jut out the sand with their colorful stalks and leopard cowries and other mollusks can be seen creeping across the bottom. The conditions allow one to move slowly across the bottom, scrutinizing every piece of coral or algae and with the large numbers of nudibranchs and flatworms if one keeps a careful eye out it is rewarding.

Sleeping parrotfish can be seen huddled up in some of the rocks as well as several species of sharpnose puffers curled around bits of algae or grass. Grumpy looking snake eels may also be seen with their heads sticking out of their burrows in the sand. Octopus can be spotted in the open or hiding in holes that seem impossible for them to get into.
