Sharks need the lateral line to locate odor sources: rheotaxis and eddy chemotaxis.
In contrast blue crabs use an odour-gated rheotaxis (Weissburg and Zimmer-Faust, 1994; Finelli et al.
There has to be some flow to serve as the directional cue which will trigger the positive rheotaxis on the juvenile, so that they move upstream.
Gastropods may use odor-guided rheotaxis and move upstream after detection of attractive chemical cues until they are able to detect and follow a concentration gradient (Croll 1983).
