Studies were made on barnacle orientations with reference to water flow seen on Grey whales taken by the U.S. Fish and Wildlife Service in March, 1969. Water flow patterns were derived by laying cord transects along lines of barnacle orientation. Statistical evaluation of directional consistency within barnacle colonies revealed that 95% of the individuals were within 14° of a mean direction. Flow patterns were generally parallel to the long axis of the whales with modification in the areas of anterior rostrum, lips, throat, and flippers. No data were available concerning water flow on the flukes.
