Parthenogenic fish
http://www.iucngisd.org/gisd/species.php?sc=118 WebParthenogenesis or ‘virgin birth’ is embryonic development in unfertilized eggs. It is a routine means of reproduction in many invertebrates. However, even though parthenogenesis occurs naturally in even more advanced vertebrates, like birds, it is mostly abortive in nature. In fact, multiple limiting factors, such as delayed and unorganized development as well as …

Parthenogenesis has been shown outside of Squamata. Its in fish, its in insects, its in amphibians. Yes, it is usually only restricted to one or two species but it is there.

This is called apomictic parthenogenesis. Mature egg cells are produced by mitotic divisions, and these cells directly develop into embryos. In flowering plants, cells of the gametophyte can undergo this process.
