And on the beach where the waves wash up can be found as well. But this species can only stay on land for a short time. After being washed up by the water, it is often unable to return to the sea and eventually dies. So if we see any Sand Dollars alive, we should take them back to the sea. Except the one found is white and looks like a flower-shaped shell. leave it like that because it is dead
For some, the Sand Dollars look a bit intimidating. But this animal is not dangerous. When holding it in your hand, you can feel Cilia’s movements. along with a small amount of yellow substance stained on his hand This substance is a pigment found in sea urchins. There is no danger to humans. So there’s nothing to worry about.
