Jellyfish has no brains Fun Facts

I hope you enjoyed the video; it was truly an eye opening experience for my fifth grade anchors. Whom were surprised to learn this jellyfish had no brains. Not to mention that the Lion’s Mane Jellyfish also ate and “pooped” through the same orifice.

That completely threw them into a hysteria. In my mind, this is good. I am hoping it peaked their interesting in learning more about this sea creature and others. If you want students to learn today, you have to offer more than just facts and figures. Educators love to throw fancy words around – like engagement. However, I find myself asking. What does that even mean?

How do you bring about engagement in a student?

Perhaps I am not educated or properly sophisticated enough to understand the proper tactics of engagement. What I do know, is that if you can capture the interest of a student. You have already won have the battle. Their interest will drive them to learn (on their own).

Forgive me for using Wow factor

To all the educators who wonder why I entertain the students with wow or grossness. I ask you to forgive me. It may disrupt your class for a few moments. It may cause your students to giggle and scoff. I believe this is your opportunity to use that to stir up interest in learning.

It could just be me. A student shocked to learn, the jellyfish has no brains. Would not this be a great opportunity to engage with your students? (Just saying.)

Have you ever seen a jellyfish? The ocean is full of jellyfish. If you have been to the beach and swam in the ocean enough times. You have most probably seen a jellyfish or been stung by a jellyfish.

Here are some interesting Lion’s Mane Jellyfish fun fact.

  • Lion’s Mane Jellyfish Can Grow Up to 120 Feet Long. The largest recorded blue whale was a paltry 108 feet long. But don’t go around calling this jellyfish the world’s longest animal. Some marine biologists claim the saltwater bootlace worm deserves that title—when fully extended. It can stretch 180 feet from end to end!
  • The Lion’s Mane Jellyfish Eats and Expels Waste through the Same Orifice. Jellyfish have a very special opening designed to perform double-duty as both a mouth and… (where they poop through).
  • Lion’s Mane Jellyfish come in a Variety of Colors. Large individuals are often red or purple. Smaller specimens tend to be shades of tannish-orange.
  • These Guys Can Have up to 1,200 Tentacles. These are arranged in eight sets that contain between 70 and 150 individual tentacles apiece. Now there is some Grade-A nightmare fuel.
  • It Makes Do With a Yearlong Lifespan. Unbelievably, one type of jellyfish may be functionally immortal. Sadly, the lion’s mane jelly does not follow suit.
  • The Lion’s Mane Jellyfish Like it cold. These large creatures are seldom seen below the northern 42nd parallel.
  • They gravitate towards the surface and almost never venture beneath depths of 66 feet.
  • The Lion’s Mane Jellyfish unlike other jellyfish, (technically) lacks a brain. They have no Brain! In all fairness, contrary to popular belief these animals do have a central nervous systems, found nestled in their “hoods” (or “bells”).
