Ocean sunfish , or Mola mola are true ocean giants – the biggest bony fish in the world . In the above photo , taken off Nusa Penida , Indonesia , a pair of longfin bannerfish act as cleaners to a 300kg fish , at a depth of about 38 metres . The left image shows an even larger sunfish in the Galapagos Islands , attended by juvenile Mexican hogfish .
A manta ray stetches out its threemetre pectoral fins to accommodate moon wrasse at Donkarlo , a well-known cleaning station in the Maldives . The mantas will allow you to approach to within a metre while being cleaned , but you have to stay low or they will disperse .
