WITH ITS FLASHY maw and bright, crimson flesh, this bizarre tropical mollusk is unlike anything else in the ocean, and it’s keeping scientists guessing with its spectacular light show.
The clams have a highly reflective tissue on the very outer edge of their mantle that is exposed and then hidden very quickly, so the change back and forth from the white reflective tissue to the red tissue creates the appearance of flashing.
