The Moon Jelly is a common ocean animal and can sometimes be extremely abundant.
This species is not threatened,but can serve as an indicator that marine ecosystems are out of balance. Unlike other larger species, they can thrive in otherwise uninhabitable waters. This means that as ocean health declines, moon jelly populations can actually increase!
Where the branches have occurred to create the more than 1,500 species though are still unknown.
While many jellies pack quite a potent stinging punch, moon jellies have stinging cells that are not strong enough to penetrate human skin, so yes you can touch one!
The most common type of stinging jellyfish is the bluebottle. These are found in non-tropical areas, especially along the south-eastern coastline of Australia. Their stings are painful, but they don't usually need medical treatment.
While box jellyfish are found in warm coastal waters around the world, the lethal varieties are found primarily in the Indo-Pacific region and northern Australia. This includes the Australian box jellyfish (Chironex fleckeri), considered the most venomous marine animal.
These stinging cells are like tiny harpoons and are triggered when the tentacle is touched, and even a dead jellyfish can sting. Because of the sting they deliver, moon jellyfish are considered annoying at beaches and to divers.
Birds, Fish and Sea turtles are common predators of Moon jelly fish.
How can you tell if a jellyfish is dead? In general, if the jellyfish has lost its typical round shape and is sort of flat, it is dead, Chacon said. However, if it is still round and freshly washed ashore, it might be alive.
Moon jellyfish are saucer-shaped and are up to 16 inches wide in diameter. You can tell the male from the female by its sex glands. The males' sex glands are pink while the females' are brown. Moon jellyfish develop in four stages: larval, polyp, ephyrae and medusa.
Moon Jelly Touch Tank
Moon jellies are easily identified by the half-circles in the middle of its bell, which are reproductive tissues. Their sting is not strong enough to penetrate human skin, so they are safe to touch.
Moon Jellies are carnivorous. They eat tiny zooplankton, mollusk larvae, crustaceans, and small fishes.
Moon Jellies are found throughout Australia.
Moon jellyfish have an average lifespan of approximately 8 to 12 months, allowing for slow growth during colder months, and faster growth during spring. After reaching sexual maturity, medusae shrink, release gametes, and typically die in the later spring and early summer season.
"It may not seem surprising that jellyfish sleep—after all, mammals sleep, and other invertebrates such as worms and fruit flies sleep," says Ravi Nath, the paper's co-first author and a graduate student in the Sternberg laboratory. "But jellyfish are the most evolutionarily ancient animals known to sleep.
Can jellyfish feel pain? Jellyfish don't feel pain in the same way that humans would. They do not possess a brain, heart, bones or a respiratory system. They are 95% water and contain only a basic network of neurons that allow them to sense their environment.
Moon Jellyfish grow (and shrink) in size depending on the amount of food they are given. For this reason they make great starter pets, as their size can be easily manipulated to the size of the tank. Our Jellyfish are sold at a young age, therefore offering you the maximum possible lifespan for your fish.
These adults reproduce via external fertilization, where females release eggs and males release sperm into the water column. Once the egg is fertilized, a larva hatches and lives in the pelagic environment for some time.
Lacking brains, blood, or even hearts, jellyfish are pretty simple critters. They are composed of three layers: an outer layer, called the epidermis; a middle layer made of a thick, elastic, jelly-like substance called mesoglea; and an inner layer, called the gastrodermis.
Instead of a brain, a jelly has a nerve net. A simple system of nerves and muscles lets a jelly pulse its bell to swim up or down as well as drift with the current. Instead of blood to carry oxygen, its thin skin absorbs it from the surrounding ocean water.
The moon jellyfish, or moon jelly, is found throughout the world's oceans. Around the size of a plate, it is recognisable by the four circles visible through the translucent white bell.
Habu-Kurage and box jellyfish are known to have extremely painful stings, Japanese sea nettle are moderately painful, and moon jellyfish are pretty much painless.
Cannonballs are one of the most harmless jellyfish. They usually only cause minor itchiness or irritation when they sting humans, and they play an important role in the diets of leatherback sea turtles and humans.
