Info
Jellyfish like Aurelia labiata are kept and shown in display aquariums around the world.
Goo without a brain?
Indeed, the jellyfish does not have a brain, but it makes every day a lot of decisions about its own movements, during ebb and flow, when touching objects, actions when acquiring food and much more.
The layer of mucus that covers the jellyfish is used to catch food sources. Cilia are hair-like structures that cover the body and transport the food
to the edge of the bell, where it is then moved to the mouth.
Prey items even include other jellyfish such as Phacellophora camtschatica and Cyanea capillata.
The jellyfish uses cnidocytes to catch prey such as small fishes
Predators:
Predators include various sea turtles and some nudibranchs, which the jellyfish loves to eat when sessile.
In addition to Aurelia labiata polyps, the shimmering thread snail (Hermissenda crassicornis) prefers to consume the sea squirt Distaplia occidentalis and the hydrozoan Obelia geniculata, while the sea anemone Anthopleura elegantissima occupies fourth place as an appetizer.
A study of mature Aurelia labiata medusae and their swimming behavior showed that touching the manubrium with a soft, hollow silicone rubber ball or a foam rubber ball caused the medusae at 1 m depth to swim to the surface.
Dense aggregations of medusae did not form within 5 meters of rock walls.
Medusae did not swim in water with salinity less than 20 parts per thousand.
In sunlight, they swam in a westerly direction.
Temporary communities:
Studies have shown that schools of juvenile pollock seek shelter under the large umbrella of the jellyfish.
All in all, Aurelia labiata is a highly interesting marine creature!
