These genetically unusual butterflies have one male and one female wing, proving that something doesn’t have to be symmetrical to be beautiful.
Beautiful bilateral gynandromorphs!!

The spotted handfish (Brachionichthys hirsutus), an amazing creature that walks the ocean floor, is a rare Australian fish from the family Brachionichthyidae. It is classified as Critically Endangered on the IUCN Red List 2002. is the first Australian marine species to be threatened with extinction.
The greatest threats to the handfish appear to be siltation and invasive species. The Derwent Estuary where the fish lives is highly urbanised and industrialised, and a range of marine pests have been introduced through shipping. One key pest is the Northern Pacific Seastar (Asterias amurensis), a particularly large and voracious predator that is now abundant in the estuary. Studies by CSIRO show that the seastars eat the stalked ascidians that the handfish use to attach their eggs.
