Mangrove areas, sand flats, or intertidal zones are places that excite me. From a distance, they may seem like silent places without movement, but up close, they are actually places full of movement. It was an environment rich with various living creatures.
Today I found some upside-down jellyfish. They live in a canal in the intertidal area which is also a mud flat on the northwest coast of Aceh.. They are Cassiopea andromeda, and that is their natural habitat.
It usually lives in intertidal sand or mudflats, shallow lagoons, and around mangroves. (Source)
Its yellow-brown bell, which has white or pale streaks and spots, pulsates to run water through its arms for respiration and to gather food. (Source)
Cassiopea andromeda is carnivorous and eats small animals from the sea or just pieces of them after it paralyzes its prey with its mucus and nematocysts when they are released. (Source)
I was aware that this jellyfish can cause a painful sting, to get the image of its bell, I turned it upside down using a wooden twig.
