Sometimes called Coronate medusa, the Atolla Jellyfish is one of the deep sea’s bioluminescent creatures. It flashes when threatened, drawing in larger predators to prey upon its attacker. This defense strategy has given it the nickname “alarm jellyfish”.
One of the most fearsome-looking creatures living in the deep, the Scaly Dragonfish inhabits warmer water at depths of at least 3,300 feet. However, despite its appearance, it rarely grows over 13 inches in length. With photophores (small, light-producing organs) running in a pattern along its body, the Dragonfish can illuminate itself and its surroundings at will, possibly to disorient predators.
