    Cryptomania is a spot we always enjoy when we’re after something a bit different in Mafia. It’s a shallow site, really, topping out around 13 metres, but the interest isn’t in the depth. Instead, you're looking at a gentle slope of rubble, sand, and seagrass, broken up by coral bommies and small caves. This is prime muck diving territory. We’ve had good luck here finding robust and ornate pipefish, often a few different octopus, and if you’re patient, you might even spot a seahorse or a frogfish tucked away. It’s definitely a site for those who like to take it slow and hunt for the smaller, more unusual critters. Visibility averages around 14 metres, which is usually plenty for getting up close with the macro life.
