Abstract

The ciliate Eutintinnus apertus (Kofoid and Campbell, 1929) was found in 18 of the 20 stations sampled near the São Sebastião region (São Paulo State). In 17 of these stations 63 (81.85%) of the total lorica was colonized by the diatom Chaetoceros tetrastichon Pavillard. Although the association between species is common, it has not been reported for neritic waters from Southwestern Atlantic before. The loricas showed a relatively constant form, but the dimensions were very variable, mainly the total lenght. Water temperature and salinity fluctuated between 23.09 °C and 25.03 °C and between 34.98 and 35.17, respectively, at the 20 sampling stations. Maximum quantities of E. apertus with Chaetoceros cells adhered were found in temperatures ranging from 24.0 °C to 24.5 °C.
