Cyanobacteria, formerly called "blue-green algae" are in the Kingdom Eubacteria.

Diatoms are beautiful unicellular eukaryotic cells in the Kingdom Protista.


These Shelf Fungi, in the Kingdom Fungi, are one of the major decomposers of the biosphere, releasing nutrients back into the soil.

Sunflowers, in the Kingdom Plantae, are members of one of the largest plant families in the world, the Asteraceae, formerly called the Compositae because each floral head is composed of numerous smaller flowers.

Lewis' Moonsnail, a large carnivorous snail of intertidal mudflats, is a member of the Kingdom Animalia, Phylum Mollusca, and is the only moonsnail on the west coast of North America.

A wading bird, the snowy egret, one member of the Kingdom Animalia, and Class Aves, looking for a meal on the mudflats at Bodega Bay, Sonoma County, California.
