Giant clams are slow growing and have a minimal defense system which makes them highly susceptible to any threat, whether from natural enemies or human threats such as unsustainable collection for seafood restaurants or the ornamental fish trade.

Malaysia’s giant clams are fast disappearing. Two of Sabah’s seven wild species, including the biggest of them all, the Tridacna gigas (which can measure up to 5ft long) have been classified as ‘locally extinct’, the other being Tridacna derasa.
