Abstract: | Scanning electron microscopy shows the form of the cupulae of free neuromasts in two species of teleost fish, and gives information about the organization of the free neuromasts in teleosts and lampreys. In lampreys some neuromasts were found to lack the surrounding moat and the flanking hillocks characteristic of the lateral line organs previously described in these fish. In all cases, the sensory cells had the kinocilium aligned with respect to the stereocilia on the longer axis of the neuromast surface, thus enabling the direction of effective stimulation of the free neuromasts to be deduced from their morphological arrangement. |
