The genus "Attheya" T. West consist of small single celled diatoms. Some of these species were earlier regarded to belong to "Chaetoceros", or to "Gonioceros", the taxonomic status of some of these species are still debated.Crawford, R.M., Hinz, F. and Koschinski, P. 2000. The combination of "Chaetoceros gaussii" (Bacillariophyta) with "Attheya". Phycologia 39(3):238-244.]

Description

They are distinguished morphologically from "Chaetoceros" by the structure of valve outgrowths or girdle bands. The girdle bands can only be seen with an electron microscope.Crawford, R. M., Gardner, C., Medlin, L. K. 1994. The genus "Attheya". I. A description of four new taxa, and the transfer of "Gonioceros septentrionalis" and "G. armatus". "Diatom research". 9:27-51.] Resting spores are seldom observed. Vegetative cells tend to attach to different substrates, including other diatoms,Tomas, C. R., Hasle G. R., Syvertsen, E. E., Steidinger, K. A., Tangen, K., Throndsen, J., Heimdal, B. R., (1997). "Identifying Marine Phytoplankton", Academic Press.] and are sometimes referred to as epiphytic. However, they are also observed to be planktonic.
