"Turner (1966) reports that a collection of Pantanodon podoxys has been made in Africa from stagnant pools. The common cyprinodontiforms in the vicinity were two species of the annual Nothobranchius which were present in similar pools. No permanent body of fresh water was found that could be inferred to have originally formed the pools. Such circumstances suggest that Pantanodon may be an annual, and therefore that annualism among cyprinodontiforms is not restricted to the aplocheiloids, but is perhaps a general characteristic of those cyprinodontiforms which inhabit ephemeral waters."
