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.

Over the last decade, materials scientists have been trying really hard to keep from getting wet. To that end, they’ve made huge strides developing coatings that so thoroughly repel dirt and water, they seem almost magic. Their secret? Recreating the nanoscale structures that some organisms employ to stay clean and dry and to redirect liquid flow.
Among researchers’ muses from the natural world are the stenocara beetle, lotus and nasturtium leaves, and the wings of butterflies. The National Science Foundation has compiled some compelling visual examples of natural and synthesized superhydrophobic surfaces. See the full video below.
