The Aquarium expands its collection of jellies
The Primorsky Aquarium's collection of jellies has increased by several dozen individuals – blue blubber jellyfish (Catostylus mosaicus) arrived at the facility from Taiwan. The species has acquired this common name due to its colouration: most jellyfish come in various shades of blue, however, white and brown specimens also occur. At the Primorsky Aquarium you can see these tropical creatures in all their natural colours.
“The blue blubber jellyfish belongs to the order Rhizostomeae and is a distant relative of edible Rhopilema jellyfish inhabiting the local waters, but of a smaller size - its bell reaches a maximum diameter of 10 cm,” said Marat Khaidarov, Principal Specialist at the Department of the Russian Far East Marine Organisms. “The blue blubber jellyfish is a tropical species found in the South East Asia, and it is widely distributed off eastern Australian coastline as well.”
Blue blubbers lead a more active life if compared with their counterparts kept at the Primorsky Aquarium: Atlantic sea nettles, upside-down jellyfish, moon and marbled jellyfish. To swim, they vigorously expand and contract their bodies that requires much energy, so they have to eat more than other jelly species. Blue blubbers feed on brine shrimp and small zooplankton. Live food for jellyfish is raised directly at the Primorsky Aquarium.
