A sand dollar can not see for it has no eyes.
No it would die immediately as they are salt water creatures.
Sand dollars survive by filter water through their exoskeletons. The live in shallow coastal waters in many different parts of the world.
Sand dollars usually are in the water, yes, but they are found on the shore because they are brought in by the tide. They aren't acctually living, they are like a type of shell, but only flat.
They live in water, if found on dry shore, they are dead or dieing! , try to throw it back into deep water!
Assuming you mean the skeleton of a sand dollar after it's dead, no it's not illegal. You can collect as many as you want. I don't think there is a restriction on keeping live sand dollars in salt water aquariums, but they are a shrinking population.
in the ocean
They live on sandy shores! Hope this helps.
Sand dollars live in ocean and they do not eat sugar. The 80% of their diet is crustacean larvea.
Because that is where they live, that way they can burrie themselves in the sand to get protection from predators.
