As a marine biologist with a love for sand dollars, I often get asked if these beautiful creatures are fragile.
Yes, sand dollars are fragile.
The short answer is yes, but there’s more to it than that.
In this blog post, I’ll explain why sand dollars are fragile, what makes them so delicate, and how you can handle them properly to avoid damaging them.
What are Sand Dollars?
Before we dive into the fragility of sand dollars, let’s first define what they are.
Sand dollars are echinoderms, which means they belong to the same family as starfish and sea urchins.
They are flat, round, and have a hard exoskeleton made of calcium carbonate.
Sand dollars live in shallow waters along the ocean’s floor and are often found washed up on the beach.
Why Are Sand Dollars Fragile?
Sand dollars are fragile because of their exoskeleton, which is thin, brittle, and easily broken. Unlike other echinoderms, sand dollars don’t have spines or any other protective structures.
Their bodies are entirely enclosed by their exoskeleton, leaving them vulnerable to damage if mishandled.
Another reason why sand dollars are fragile is that they are sensitive to changes in their environment. They rely on the ocean’s currents to move around and get their food.
If they are disturbed or moved from their natural habitat, they can become stressed, causing their exoskeleton to weaken and break.
How to Handle Sand Dollars Properly
If you come across a sand dollar on the beach, it’s essential to handle it with care. Here are a few tips on how to handle sand dollars properly:
- Hold them gently: When picking up a sand dollar, use a light touch and hold it gently. Avoid squeezing or putting pressure on its exoskeleton, as this can cause it to break.
- Avoid touching the spines: Some species of sand dollars have tiny spines on their exoskeleton. These spines are sharp and can pierce your skin. Be sure to avoid touching them.
- Keep them in the water: If you’re planning on moving a sand dollar or taking it home, keep it in the water as much as possible. Sand dollars need to be in the water to survive, and taking them out of their natural habitat can cause them to die.
- Don’t use chemicals: Avoid using any chemicals or cleaning agents on sand dollars. These substances can damage their delicate exoskeleton and harm them.
What Happens When Sand Dollars Die?
When sand dollars die, their exoskeletons can wash up on the beach and be found by beachgoers. These exoskeletons are often referred to as “sand dollar shells” and are popular souvenirs.
However, it’s important to note that these shells are not the same as live sand dollars. Live sand dollars are brown or purple and have tiny spines covering their entire exoskeleton.
Sand dollar shells, on the other hand, are white and have no spines.

Conclusion: Are Sand Dollars Fragile?
In conclusion, sand dollars are fragile creatures that need to be handled with care. Their delicate exoskeleton makes them vulnerable to damage, and they are sensitive to changes in their environment.
If you come across a sand dollar on the beach, remember to hold it gently, avoid touching the spines, and keep it in the water as much as possible. If you’re lucky enough to find a live sand dollar, admire its beauty in its natural habitat and avoid taking it home as a souvenir.

FAQs
Do sand dollars break easily?
Yes, sand dollars are fragile and can break easily if mishandled or dropped.
How do you make sand dollars less fragile?
Sand dollars can be made less fragile by soaking them in a mixture of water and white glue, which will strengthen their structure and prevent them from breaking easily.
However, it is important to handle them gently and avoid dropping or crushing them to further protect their delicate nature.
What happens if you break a sand dollar?
If you break a sand dollar, it will likely crumble into small pieces as it is made up of fragile, calcified plates.
Are Broken sand dollars still alive?
No, broken sand dollars are not alive.
They are the remains of a dead sand dollar.
Are dead sand dollars fragile?
Yes, dead sand dollars are fragile and can easily break or crumble.
How do you keep a sand dollar from breaking?
To keep a sand dollar from breaking, handle it gently and avoid applying too much pressure or force.
Additionally, storing it in a protective case or wrapping it in tissue paper can help prevent damage.
