Considering that H. hippopus does not have a mantle that overhangs its shell, is it safe to say that it has a smaller mantle volume than similarly sized tridacnids? If so, does it have a similar density of zooxanthellae in its mantle relative to other tridacnids? If H. hippopus does have less zooxanthellae, would this make this clam more reliant on filtered particulate matter, namely phytoplankton?
