Palau is home to seven of the world's nine species of giant clams, and I have three or four of them documented here (the pictures in my invertebrate guide aren't giving me much to distinguish
T. maxima from
T. squamosa, so I'm more or less making it up in the captions below). Like corals and the Jellyfish Lake jellyfish, giant clams have a symbiotic relationship with algae, which provide nutrients as well as brilliant color.
