The deep sea anglerfish lives at the very bottom of the sea. Although it’s not the most attractive fish, it has a very unique feature. The female anglerfish has a piece of dorsal spine, tipped with glowing flesh, that comes out of its mouth. This luminous rod attracts prey close enough for the anglerfish to catch it. Because the anglerfish’s mouth is so big and its body is pliable, it can swallow prey up to twice its size.
Bonus Fact: The anglerfish’s light glows because of millions of bioluminescent bacteria.
