Aurelia aurita | Moon jellyfish
The moon jellyfish is a member of the escifozoos class of jellyfish and one of the most abundant and common in all the world’s oceans, mainly in coastal areas. It has four (or 5 to 7 ) horse shoe-shaped gonads which are symmetrically arranged. In females the gonads, or “moons” are pink in colour, whereas in males they are white. Moon jellyfish feed on zooplankton and small invertebrates such as crustaceans, and polychaetes. They use their tentacles to capture and paralyse their victims and guide them up to the mouth. Moon jellyfish swim by contracting their body with regular undulations. They stay near the surface, often travelling adrift on currents. Sometimes they are found stranded on the coast in large numbers, as they are not good swimmers. Their sting generally does not bother humans.
