What is the shelled sea animal?
Mollusks are creatures that have a soft body with a muscular foot that is generally surrounded by a tough calcareous exoskeleton or shell. All mollusks have a special fleshy organ called a mantle which allows them to form the shell. Some mollusks have two shells, eg. clams, cockles, mussels, oysters and scallops.
Which animal has a shell on its body?
Armadillos are the only mammal that has a shell. The armadillo (Dasipodidae) is the only mammal that has a shell.
What is shell in zoology?
A shell is a hard outer layer, which has evolved in a very wide variety of different animals, including molluscs, sea urchins, crustaceans, turtles and tortoises, armadillos, etc.
What is inside a shell?
Shells are made of calcium carbonate, in the mineral form of calcite or aragonite. Animals build their shells by extracting the necessary ingredients—dissolved calcium and bicarbonate—from their environment.
What lives in a shell?
Snails and turtles and crabs and clams all have shells that act as their homes and protect them from harm. ... Young readers will love exploring the fascinating homes of creatures like hermit crabs, scallops, and turtles.
What reptile has a shell?
Turtles and tortoises are reptiles with shells. Turtles live mostly in the water and tortoises live mostly on land.
Does an octopus have a shell?
Most people are familiar with octopuses in the Incirrata group. They have soft bodies and no internal shell (or in some species two small rods made of cartilage), which allows them to squeeze their bodies through unimaginably tight spaces.
Which animal has shell on its back?
Armadillo is a Spanish word meaning “little armored one” and refers to the bony plates that cover the back, head, legs, and tail of most of these odd looking creatures. Armadillos are the only living mammals that wear such shells.

Crabs have thick shells covering their bodies. The shell does not grow in size, so the animal has to keep shedding its shell several times as it grows.
What is shell in science?
Scientific definitions for shell
A set of electron orbitals that have nearly the same energy. Electrons in outer shells have greater energy than those in shells closer to the nucleus.
What are the animals have two shells?
Bivalves are mollusks with two shells such as clams and oysters. Univalves are animals with one shell such as a snail. Mollusks without shells include squid, banana slugs, and octopi. Some mollusks are terrestrial, occurring in most environments on earth, while others live in the water for some or all of their life.
What do sea shells eat?
Some do feed on fixed animals (sponges), on algae, on grass, on other marine gasteropods, on worms, on fishes, on dead animals (necrophagous shells). Cone Shells are predators and their feeding habits are complex.
What are snail shells made out of?
Seashells are the exoskeletons of mollusks such as snails, clams, oysters and many others. Such shells have three distinct layers and are composed mostly of calcium carbonate with only a small quantity of protein--no more than 2 percent. These shells, unlike typical animal structures, are not made up of cells.
Is the shell part of the turtle?
A turtle can't crawl out of its shell, just like we can't crawl out of our own skeletons. In fact, the shell is actually part of a turtle's skeleton, comprised of the ribcage, vertebrae, and sternum. But if you could peer inside a turtle shell, you'd find some of the most unusual features in the animal kingdom.
What does it mean to be in a shell?

Who lives in a sea shell?
All those seashells you find on the beach were actually once home to small, soft-bodied creatures called molluscs. Clams, pipis, scallops, mussels and oysters are all different types of molluscs.
How is a shell made?
As mollusks develop in the sea, their mantle tissue absorbs salt and chemicals. They secrete calcium carbonate, which hardens on the outside of their bodies, creating a hard shell. ... When a mollusk dies it discards its shell, which eventually washes up on the shore. This is how seashells end up on the beach.
