Clams light up the deep

Disco clams produce flashy displays by bouncing light off reflective strips located on their lips. Susan Milius described marine biologist Lindsey Dougherty’s research on these aquatic spectacles, which might help clams lure in small prey, in “Disco clams put on a streak show” (SN: 2/8/14, p. 5).

“The display is striking and it’s astounding that it’s not bioluminescence,” online reader Brian Howells wrote.
