The 5 Traits Of Invertebrates

Invertebrates have five main traits: They are multicellular, they have no backbone, they can't make their own food, most of them can move, and they do not have cell walls.

1. When we say that an invertebrate is multicellular that means that all of its cells are working to increase the survival of the creature. All the cells have specific duties to preform.  
2. All the invertebrates have no backbone which their name implies. Thus, most of the invertebrates can bend their bodies here, there, and everywhere like the stick bug.
3. Invertebrates, unlike plants, cannot create their own food. The word used to describe animals that do not make their own food is heterotrophic.
4. Invertebrates do not have cell walls. A cell wall is a rigid or semi-rigid envelope outside cell membranes of plants and fungi.
5. Most invertebrates can move, even some sponges when they are young can move, but sadly these moving sponges grow old and die. Some invertebrates like spiders and octopuses move all their lives.
