Study Notes

What Is a Jellyfish?

  • Jellyfish are sea creatures that have been floating around Earth's oceans for millions of years.
  • They are invertebrates, or animals without backbones, and have no bones at all.
  • They are made of a slimy, jelly-like material, which is how they got their name.
  • Their bell-shaped bodies are translucent, or almost see-through.
  • They lack a heart, blood, and a brain, making it difficult for them to swim, so they tend to float through water, moving along with the currents.

What Do Jellyfish Eat?

  • Jellyfish are carnivorous animals that eat meat and feast on other sea creatures.
  • They can be opportunistic predators, eating just about anything they float into.
  • Their diet depends on their size, with smaller jellyfish eating plankton and larger ones preying on fish, shrimp, and crab.
  • The largest jellyfish may even consume other jellyfish.

Unique Features of Jellyfish

  • Jellyfish have long tentacles that trap their prey, sometimes using toxic venom to kill it.
  • Oral arms, like fuzzy ribbons, bring food to the mouth.
  • The mouth is a small hole located underneath the bell-shaped body.
  • Since jellyfish bodies are translucent, the food inside is visible from the outside.

Jellyfish Blooms

  • Large groups of jellyfish that drift together are called blooms.
  • Blooms can consist of millions of jellyfish, negatively impacting other ocean animals.
  • These blooms can lower the population of small fish, crab, shrimp, and plankton, making them more difficult to find.
