✦ Synopsis
The filtration rate has been determined for Electra pilosa and Conopeum reticulum, acclimated at 4 constant tempers~ t~res (6 ~ t2 ~ 18 ~ 22 ~ Cryptomonas sp. was used as the test food-organism. Temperature affec%s filtration rate in both bryozoans. Clearance rate, measured at hourly intervals during the course of the experiment, was never nniform. Possibly, temporary reductions in ciliary ac~iviLios were induced by the artificial conditions under which the experiments were carried out. The results obtained compare well with those reported by Bullivant (1968) on Bowerbankia imbr/cata, a cosmopolitan etenostome. Rate of food passage through the Mime~taxy canal is affected by temperaVure. The prosant study is the first to demonstrate the effect of temperature on the rate of filtration in bryozoans.
