Ladybirds are insects; all insects have an external skeleton without a backbone.
Because there would be nothing to move the skeleton, if we didn't need muscle we wouldn't have it
Without your skeleton system, you would be a useless blob. Your skeleton helps you stand up, move, and do everyday things, including LIVING!
Without a spine you can not stand. Without ribs your guts aren't held together, without leg bones you can't move. Your skeleton help you stand up, without it, you'd be like an airhead, and be all wiggly, you wouldn't be able to move.
There are animals that can move their bodies without bones, for instance worms and insects have no bones.
None. Butterflies are insects, and insects don't have bones. They rely on exoskeletons instead.
Insects have an 'exo-skeleton' or outer-skeleton - instead of an internal bone structure.
Yes all insects have an exoskeleton.
insects and crustacaens
no
Butterflies have a hard exoskeleton called the exoskeleton that provides support and protection. Their exoskeleton is on the outside to help them maintain their shape and structure. The exoskeleton also provides attachment points for muscles, allowing butterflies to move and fly.
because it forms the outer skeleton of arthropods including insects..
