A family or group of foraminifers (single-celled marine organisms) with shell structures characterized by net-like or reticulate pore patterns.
From Greek 'dictyon' (net/mesh) and 'nema' (thread), with the taxonomic suffix '-ina.' The name references the netted appearance of their microscopic shells, which have pores arranged in distinctive mesh patterns.
Dictyonina foraminifers are so tiny you need a microscope to see them, but even at that scale, they create shells with intricate net-like patterns—it shows that nature creates mesh designs at every scale, from the microscopic to the visible.
