Modifications of caudal fin The transition from heterocercy to homocercy is
evidently available in a number of fossil bony fishes. But the example from the
living bony fishes is also not rare. The primitive groups like Holosteans which
includes ...

Contributions from the Zoological Laboratory
Taking a glance at our figures, we may readily verify the fact that heterocercy
seems to be tending towards gephyrocercy as the final term of caudal
differentiation. On PL I, Fig. 1, the archicercal filament of Chimcera [69] • THE
EVOLUTION OF ...

Having discussed the probable stimulus effecting heterocercy, there still remains
the question as to why it was at all necessary to develop this asymmetry. When
we remember that heterocercy is but a stage in the production of homocercy, it is
...

The dorsal finlets at this stage are merely a continuation forwards of the finfold of

The elasmobranch fishes
In Hoterodontas (fig. 78.x) the radials are more numerous than are the vertebrae.
In Lomiio the dorsal radials are inconspicuous, while those having a ventral
position are usually large. In this type we see the extreme of heterocercy, in
which ...
