Bear paw clam near Rongelap Atoll in the Marshall Islands (@ Andre Seale /Aurora Photos)
- It\s unclear where Hippopus hippopus got such an unusual name.""They tend to clam up under questioning
- Giant clams are used to taking their place in the spotlight.""It doesn\t get much bigger than Sesame Street
- We ventured to the Marshall Islands for this photo.""Any idea where that is?
- The blue streaks of this creature are its inner shell, an extra layer of protection from predators.""But what does that copper-spotted oval do?
