The video explores the fascinating world of foraminifera, tiny amoeboid protists with hard shells. These organisms have existed for over 500 million years, evolving into thousands of species. The video discusses their historical significance, types, structures, and their role in geology. It also narrates a journey of foraminifera fossils from Virginia to Poland, highlighting their resilience and importance in understanding Earth's history.

What is the main difference between benthic and planktonic foraminifera?

• Benthic foraminifera live on the ocean floor, while planktonic foraminifera float near the surface.

• Benthic foraminifera are larger than planktonic foraminifera.

• Planktonic foraminifera are found in freshwater, while benthic foraminifera are in saltwater.

• Benthic foraminifera have no tests, while planktonic foraminifera do.

What is the function of pseudopodia in foraminifera?
