Spotted Lagoon Jellyfish (Mastigias Papua)


Spotted lagoon jellyfish (Mastigias papua) are a very popular species within the aquarium trade. They have white spots throughout their semi- translucent body with a variation of base colour, including pale blue, green, pink, orange, and yellow. This colour variation is thought to be dependent on thee symbolic algae in their body. Although they are often described as same species, ones found in Indo-Pacific seas, jellyfish lake in Palau and East China sea are most likely different species of Mastigias. The energy produced by the photosynthesis of the symbiotic algae provides a large portion of their energy requirements. They inhabit quiet lagoons and harbours and migrate daily towards sunlight. Often seen in public aquariums, this species is less commonly kept as a pet jellyfish. Full spectrum light is required to keep this species.
