Without Backbone
અકરોડધારી
Animals with no backbone inside
Without backbone = no spine inside. The hard part is often on the outside.
Say it like this: no backbone = soft or hard on the outside, not a spine inside. Insects, worms, snails, crabs, and spiders all belong here. Most animals on Earth have no backbone!
