Cannibalism is observed widely across animal groups and can be beneficial within populations. We have discovered that tadpoles of the Pugh’s mountain frog (Philoria pughi) consume unhatched sibling embryos. This form of siblicide has been rarely described among amphibians and could be exploited in captive breeding programs for Philoria species. Photograph by Michael Mahony.

Kultarrs are widespread over much of inland Australia. Although only two subspecies are currently recognised, we show that a third may be present in Western Australia. We also suggest that the long-tailed dunnart be recognised as a second species of Antechinomys as A. longicaudata.
