Largest organisms . "Pelagornis sandersi" is thought to have had an even larger wingspan of about , but is only about , half the mass of the former. The following is a list of the heaviest living bird species based on maximum reported or reliable mass, but average weight is also given for comparison. These species are almost all flightless, which allows for these particular birds to have denser bones and heavier bodies. Flightless birds comprise less than 2% of all living bird species. The largest living amphibian is the Chinese giant salamander ("Andrias davidianus"). The maximum size of this nearly human-sized
