Sand dollars grow and develop their unique skeletal structure through a process called biomineralization. They absorb calcium carbonate from the ocean water and use it to build their hard, flat skeletons. As they grow, the sand dollars' skeletons develop distinctive patterns of pores and spines, which help them move and protect themselves.

How many bones are in moose?
Moose typically have around 207 bones in their skeletal structure. This number can vary slightly due to individual differences and variations in species. Like other members of the deer family, moose have a complex skeletal system that supports their large size and unique adaptations for their environment.
What structure is found in cardiac muscle tissue but not skeletal muscle tissue?
Intercalated discs are unique to cardiac muscle tissue, providing a strong connection between adjacent cells and allowing for coordinated contraction of the heart. Skeletal muscle tissue lacks intercalated discs since individual muscle fibers act independently.
Which structure is not unique to plant cells?
The nucleus is a structure not unique to plant cells.
What are the three types of muscles and how do they differ in terms of structure and function?
The three types of muscles are skeletal, smooth, and cardiac muscles. Skeletal muscles are attached to bones and are responsible for voluntary movements. They have a striped appearance due to their organized structure of muscle fibers. Smooth muscles are found in organs and blood vessels, and they are responsible for involuntary movements. They have a smooth appearance and are not under conscious control. Cardiac muscles are found in the heart and are responsible for pumping blood throughout the body. They have a unique branching structure and can contract rhythmically without fatigue.
How do cats jump with such agility and grace?
Cats are able to jump with agility and grace due to their powerful leg muscles and flexible spine. Their unique skeletal structure and keen sense of balance also contribute to their ability to leap and land with precision.

How does a Sloths skeletal system work?
A sloth's skeletal system supports its body by providing structure and protection to vital organs. Their unique anatomy, including long limbs and curved claws, helps them hang from trees for long periods without exerting much energy. Their slow metabolism also contributes to their slow movement and helps conserve energy.
What structure is unique to the lamprey?

Which structure is unique to plants?

What is unique about an aye-aye's appearance?
The aye-aye has a mix of traits found on other animals, so there is nothing "unique" about it's appearance. However, the combination of traits is unique for primates. They have a fox-like tail, bat-like ears, ever-growing front teeth (like a rodent), and a skeletal middle finger. (The striped possum from Australia also has a skeletal finger, so even this trait is not unique.)
