What are some examples of animals without bones?

Invertebrates are animals that lack a backbone, or vertebral column. They make up over 95% of all animal species on Earth, and come in a variety of shapes and sizes. Here are some examples of animals without bones:

  • Jellyfish are soft-bodied creatures that float through the water. They have a bell-shaped body with tentacles that they use to catch food.
  • Sea urchins are spiny-skinned animals that live on the ocean floor. They have a hard, round body covered in spines.
  • Starfish are also spiny-skinned animals that live on the ocean floor. They have a central disc with five or more arms.
  • Worms are long, thin animals that live in soil, water, or other moist environments. They have a soft body and no appendages.
  • Insects are six-legged animals that live in a variety of habitats. They have a hard exoskeleton and wings.
