Invertebrates

NOTES: The following list is necessarily a preliminary account of the invertebrate diversity at BFS. Most species on this list exist in a reference collection in the Department of Biology, Pomona College. Please send records (and where possible, specimens) of additional species to J. C. Wright.

Photos: Links labeled ‘BFS’ are pages created for the Bernard Field Station. Photos on the BFS pages may be used for any personal or academic purposes as long as notification of use is sent to the BFS Webmaster and the image is clearly credited with ©[Name of photographer]. For higher-resolution images, please contact the photographer. Note that no photos taken at the BFS may be used for commercial purposes without the express permission of the Claremont University Consortium. You must have pop-ups enabled to view the BFS pages.

‘CP’ links will return all photographs of the listed taxon in the CalPhotos, Digital Library Project database. As indicated above, some of these taxa may not, in fact, occur on the BFS. Note that you must check the stipulations with each photograph for permissible uses of the CalPhotos images.
