This colony of Cassiopeia Jellyfish, is also known as the “upside down Jellyfish”
Cassiopeia are often mistaken as Sea Anemone, though they can sting it is not very venomous or deadly, they also do not sting very often.
These particular type of Jellyfish are filter feeders. They extend their frilly tentacles up into the water column where they capture Planktonic food and absorb light that is used by photosynthetic algae that are housed in their tissue.
