In summer there is an abundance of sand dollars but not in the winter - where do they go in the cold weather?

Answer 1

In winter, sand dollars tend to burrow into the ocean floor or move to deeper, warmer waters to avoid harsh conditions and predation. This behavior helps them maintain their energy reserves and survive until warmer temperatures return in the summer. Additionally, sand dollar populations can be affected by seasonal changes in food availability and environmental factors, which may contribute to their reduced visibility during colder months.
