Quinqueloculina seminulum and Quinqueloculina agglutinans are two members of the Tubothalamea family of the foraminifera. The first has a wall made of calcium carbonate and the second has a proteinaceous wall embedded with mineral particles (hence it is "agglutinated"). The wall of each foram is semi-transparent and inside the living versions the cytoplasm appears pink or orange due to the presence of algal symbionts.

What you can see below in the movies are the pseudopodia of live versions of these foraminifera
