It’s the spookiest time of year again: Halloween! For most people, it’s the only time of year that it’s appropriate to dress up like something gross or creepy and scare the living daylights out of unsuspecting children and adults, day or night. But for some creatures in the ocean, looking gross or creepy is just a hard fact of life, one that we hope comes with the benefit of having few natural predators. So in honor of Halloween, we bring you some of the ocean’s spookiest creatures that you can look forward to seeing in your nightmares tonight. Have fun and be safe in your scary adventures!
