I am studying the visual behavior of two species that simultaneously view in
air and water:  Anableps anableps and Pantodon buchholzi (Osteoglossomorpha).

The behaviors are clear and at some point I will send summaries.
My question to the list is this:
        Does anyone have information about the natural histories of these
species?  I am trying to relate my laboratory findings to their natural
histories and because of their relative obscurity (especially Pantodon), I
have found little. I am particularly interested in the natural history
related to vision and visual behavior.
      For instance, who are their predators?  Since they both live so close
to the surface, I infer that some birds might prey on them, but is it so?
Since they are so close to the surface, they provide a nice target for
predators from below as well. Is there any info about this?

        Please respond directly to my email ([log in to unmask]).

        Many thanks.
