A hard shell animal? Like a crab or snail?
sulg is same as snail

No; the shell grows as part of the snail.
armadillo Armadillos aren't reptiles, they are mammals. Tortoises are totally terrestrial (live on land) and have a hard shell.
Snails have a shell to protect them from predators. Snails also use their shell to keep their vulnerable organs from exposure to the elements.
The spine in vertabrates(animals with backbones) or shell of a snail.
Snail crab shrimp etc
Mollusc's have a hard outer shell . For example a mollusk would be a snail and there's even more .Here are examples of a mollusks snail , slugs , clams , oysters , squids and octopus . And also not all mollusks have an hard outer shell for example it would be a slug or a squid they both don't have a hard outer shell . This group is a part of the invertebrate theme.
woodlouce !!!
it looked like something like todays octopus but had a hard shell on its head. the shell looked something like a snail shell when curled up but epands.
If the snail(s) are still transparent then if the fish see it they will most probably eat it because its shell is not hard enough to protect it.
