This jellyfish species has a very short life span of one year. Then they transform into a polyp, and then they go into the ephyrae stage, and finally the medusa. Lion’s mane jellyfish go through four life stages. Once they grow over 18″ they end up a dark brownish-red. Those between 5″ and 18″ are more of a red or yellowish-brown. Smaller jellyfish with a bell size less than 5″ are usually yellow or pink. Similar poisonous nematocysts protect the upper portion of the bell. Tentacles are typically yellow or red with purple oral arms. The top of the bell is usually red or dark yellow with a thick center that thins as it gets closer to the edge. These same nematocysts cover the oral arms.
Now, each tentacle – or appendage – has nematocysts that contain potent neurotoxins that can be harmful to humans. There are also wide oral arms that extend out of the mouth. That means one lion’s mane jellyfish can have up to 1,200 individual tentacles that can grow up to lengths over 100 feet.Įach lobe also contains a rhopalium or balance organ. Eight clusters, arranged in four rows, surround the jellyfish’s mouth, which is on the bell’s bottom.Įach cluster, or lobe, contains up to 150 tentacles a piece. Lion’s mane jellyfish have a bell-shaped body with flowing tentacles dangling from the underside.
The bell can vary from smaller than an inch up to almost ten feet. The warmer the climate, the smaller they grow. The length of a lion’s mane jellyfish’s tentacles can vary between 30 to 120 feet. Species living in lower latitudes are a smaller size than those in the north.īecause lion’s mane jellyfish is one of the largest in the world, it makes sense that these creatures, although made up of 95% water, can weigh up to 200 pounds. Lion’s mane jellyfish range in size, depending on their location. Fun Facts About the Lion’s Mane JellyfishĬharacteristics & Appearance Weight & Length.What Does the Lion’s Mane Jellyfish eat?.Where Does the Lion’s Mane Jellyfish live?.Turns out the space jelly babies (which should be the name of the next Muppet movie) did turn out to have issues navigating on Earth after being raised in a place without gravity.Īs Elton John told us in “Rocket Man,” space “ain’t the kind of place to raise your kids. We humans also have calcium crystals in our inner ears that help us understand gravity’s pull. There are calcium sulfate crystals in a moon jellyfish’s bell that move with gravity, telling the jellyfish whether it is moving up or down. This would provide insights on how human space babies might be affected since both jellyfish and humans need gravity to orientate themselves. They wanted to see how being raised in a low gravity situation would change jellyfish behavior once they were back on Earth. jellyfish babies) on a trip that was out of this world. Yes, living up to their lunar namesake, moon jellies took a trip to space! In 1991 NASA launched over 2,478 jellyfish polyps (a.k.a. Plus, they are pretty slow, making it easy for their predators to have a lazy afternoon lunch. Their clear gelatinous structure might not look nutritious, but moon jellyfish contain some fatty acids crucial to growth and reproduction. Moon jellyfish are considered a delectable snack by all sorts of turtles, birds and fish. Scientists are studying this unique method of locomotion to inspire the ways future underwater robots might move. As a moon jellyfish opens and contracts its bell, it creates a vortex, several vortices, in fact, that create a high-pressure wall of water that becomes its runway to blast off. They are able to create a pocket of water to project themselves. Jellyfish don’t need fins or skeletons to swim they use their bells. But if you happen to be a plankton or mollusk that has learned to read and found access to the internet, well, I have bad news: That jellyfish sting is going to immobilize you to become the jellyfish’s next meal.
Don’t let this scare you away from these beautiful creatures! Their sting has little effect on humans beyond slight discomfort and a rash that will last only a few hours.
Moon jellyfish can sting with their tentacles. They have short wispy tentacles that hang below and tend to float just below the surface of the water. They are best identified by four purple glowing circles on the top that loop around in a clover-like formation.
MOON JELLYFISSH FULL
Moon jellyfish get their name from their translucent bell-shape that looks a bit like a full moon. It felt as if we had crossed over into some alien dimension, the rocky coastline transformed into a sea filled with these other-worldly creatures. Once on a family vacation, we wrapped up a hike at Acadia National Park to find hundreds of moon jellies floating near the shore. Moon jellies have a special place in my heart.
