Crown Jelly

Crown jellyfishes are distinguished from other jellyfish by the presence of a deep groove running around the umbrella, giving them the crown shape from which they take their name.

They are found in deep water during the day where the water is cold, then at night they come to near the surface drifting in bays, lagoons and estuaries to feed on zooplankton.

Crown Jellyfish have a cone shaped swimming bell that reach 20cm tall and 17cm in diameter, however zoological specimens from the ocean usually are less than 5cm in size.

the Crown jellyfish undergoes straight up and down movement from deep water in the daytime to shallow water at night in order to follow their prey, or catch their prey. They will swim downward when exposed to a bright light. Crown Jellyfish produce plentiful amounts of mucus which has the capacity of bearing stinging cells.

Crown Jellyfish are mostly found at mesopelagic depths (between 200m and 1000m, called the twilight zone) in all oceans worldwide, but mostly in the Pacific Ocean and Atlantic ocean. Furthermore, they are mostly found in the New Guineas or the ocean nearby. Populations a magnitude greater than the open ocean have been found in Norwegian fjords, especially Lurefjorden. They live in depths below 900m where the water temperature is only 7 degrees Celsius (45 F).
