The biggest are giant clams, Tridacna gigas. Their twinned shells can grow to well over a metre across and tip the scales at 200kg, the same as two newborn elephants. Giant clams, like all shell-making molluscs, sculpt their protective homes from calcium carbonate and gradually expand them throughout their lives.

Is shell an animal?

A seashell is usually the exoskeleton of an invertebrate (an animal without a backbone), and is typically composed of calcium carbonate or chitin. ... While most seashells are external, some cephalopods have internal shells. Seashells have been used by humans for many different purposes throughout history and prehistory.

Do squid have shells?

Is Squidward a squid?

Despite his name, Squidward Q. Tentacles—the grouchy neighbor of SpongeBob SquarePants in Nickelodeon's long-running cartoon—isn't a squid. He's an octopus. (Allegedly, creator Stephen Hillenburg named him Squidward because “Octoward” sounded too weird.)

What is shell of the turtle?

A turtle's shell is as much a part of its body as our skeleton is to ours. The shell is made of two pieces, the carapace (top) and the plastron (bottom), which are fused together on each side at what's called a bridge. The carapace is covered by an outer layer of individual pieces called scoots.

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.

Are turtle shells exoskeletons?

The turtle shell isn't like any other protective element of any living animal: it's not an exoskeleton, like some invertebrates have, nor is it made of ossified scales like armadillos, pangolins, or some snake and reptile species. ... The turtle shell is actually a peculiar evolution of a turtle's bone structure.
