Interesting Facts about Jellyfish
On World Jellyfish Day, let’s get to know the world’s most astonishing invertebrate.
- Jellyfish have tentacles armed with tiny, stinging cells which they use to stun or paralyze prey before gobbling it up.
- These incredible invertebrates have no brain, heart, or bones. Most jellyfish species don’t even have eyes.
- Jellyfish have a small mouth in the center of their body – and use it for both eating and discarding waste. Also, by squirting water from their mouths, Jellyfish propel forward.
- Jellyfish don’t have lungs, gills, or any other part of a normal respiratory structure. They absorb oxygen through their skin.
- Unlike most species of jellyfish, box jellies have eyes – 24 of them spread across all four sides of their bell, giving them a 360-degree vision.
