Unlike vertebrates, which typically have an internal skeleton or endoskeleton, snails have an external skeleton called an exoskeleton. Their exoskeleton is in the form of a hard, coiled shell that protects their soft body parts and internal organs. This shell helps provide structural support, allowing snails to carry out their daily activities without the need for bones.
Do Snails Have Skeletal System?
Snails are classified as invertebrates, which means they do not possess a backbone or spinal column commonly found in vertebrates. Their unique anatomy sets them apart from other creatures with bones. Instead of bones, snails have a muscular foot and a structure called the visceral mass that protects their internal organs.
In terms of respiration, snails do not rely on their mouths to breathe. Instead, they have a breathing hole beneath their shells, which is another characteristic that distinguishes them from creatures with bones.
