rheotaxis [¦rē·ə¦tak·səs]
(biology) Movement of a motile cell or organism in response to the direction of water currents. Rheotaxis the property of certain lower plants (myxomycetous plasmodia), unicellular animals (flagellates, infusorians), and cells (spermatozoa) to move in a direction opposite to the current of a fluid.

No references found | Starfish have well developed chemoreceptive and rheotactic capabilities (Sloan 1980) and it is likely that they were attracted by odors emanating from mussels damaged by the mussel dredges. The behavior of fish in response to trawls has been described as a combination of optomotor response and rheotactic reaction, both of which contribute to a fishes' ability to escape capture in a trawl (Watson (17)). Because the water flow from the mussel's exhalant siphons can be expelled over quite a distance, in addition to rheotactic response, filtering may also act as a sort of chemical beacon to guide the commensals in their search for the appropriate partner (Gotto 1970). |
