Zoologists study animals but the animal kingdom has too many animals for one person to know all about. So, most zoologists focus their study on a particular group of animals.

For example, invertebrate zoologists are mostly interested in animals without backbones. Again, that is an enormous group of organisms; far more than one person could manage.

Most invertebrate zoologists narrow their interests to a fraction of those. For example, zoologists who study insects are called entomologists. Given that there are millions of species of insects in the world, one entomologist might further narrow his or her focus to one family of insects, such as the insect life in the streams of California. Other entomologists become lepidopterists because they are particularly fascinated by butterflies and moths, known as the family Lepidoptera, meaning “scale wing” in Latin.

Christopher Rogers is an invertebrate zoologist from the Central Valley. He mostly studies the fairy shrimp that live in vernal pools. He has become one of the world’s foremost experts on fairy shrimp. 

When he isn’t traveling all around the world searching out new species of fairy shrimp, Christopher lives and works right in Woodland, CA. If you want to know where Christopher found fairy shrimp longer than your longest finger, check out Christopher’s profile.
