When we talk about animals, we often picture creatures with bones– the kind that help them stand, swim, fly, or crawl. But not every animal is built that way. In many parts of nature, there are species that live their entire lives without a single bone in their body. These animals are known as invertebrates, and they’ve adapted in their own unique ways to survive without a skeleton.
Here are a few well-known examples of animals that manage just fine without bones.
