✦ Synopsis

Gravitational factors appear to influence the establishment of bilateral symmetry in amphibia, birds, elasmobranchs, chondrostean fishes, and teleostean fishes. Correlations between the plane of symmetry and the planes of the first or second cleavage have similarly been noted. Evidence is presented indicating that neither the direction of gravity nor the first or second cleavage planes can be correlated with the orientation of bilateral symmetry in the Japanese ricefish, Oryzias latipes. An alternative explanation for the previous data supporting a gravitational influence in teleostean fishes is offered.
