show:
name:Benthic foraminifera
info:~
There are two species of Foraminiera: longitudal and coiled. The first chamber of the longitudal species has orange marks. Haploid and diploid generations alternate in both species. All chambers of the haploid generation have the same size. In the diploid generation, subsequent chambers are bigger than their predecessors. 

Nutrients are shown as tiny green cylinders. Foraminifers move towards nearest nutrients and this way they can accumulate enough energy to reproduce.

When the "Enhance visualization" option is enabled, reticulopodia are shown as large disks and positions of nutrients are indicated by cuboids.
