Moon Fish

The first diver to have ever encountered a Moon Fish must have been given quite a fright. Measuring up to three metres from head to tail — and sometimes over four metres from fin to fin — this is an immense creature indeed.

Large it might be, but the Moon Fish is no threat to divers. Recovered from the initial shock? Swimming alongside this gentle giant is a rare treat indeed.

The Moon Fish has several names — including, somewhat confusingly, the Ocean Sunfish — but its moniker matters little to those keen to get up close and personal. Found in temperate and tropical waters around Southern California, Indonesia and New Zealand, the so-called Swimming Head (another nickname, this one that points to the Moon Fish’s unusual shape) is calm and shy.

Happiest swimming close to the ocean surface, the massive Moon Fish can weigh up to 1,000kg — making it the heaviest bony fish on Earth. Impossible to miss, this is one to discover on your next dive trip.
