At midnight and silty depths of Tasmania’s Derwent River, an uncommon sort of fish might be discovered strolling – not swimming – alongside the riverbed. The noticed handfish, which strikes utilizing pectoral fins that appear like fingers, lurks within the murky depths, able to pounce on any prey it attracts with the fluffy lure above its mouth.
Its cream coloring and darkish brown or orange spots mix in with the sandy flooring, making the fish arduous to identify, and even more durable to {photograph}. This, coupled with the truth that the species is critically endangered, with fewer than 3,000 people thought to stay within the wild.
However French photographer Nicolas Remy was decided to see the elusive fish for himself. In 2022, he traveled from his base in Sydney to Australia’s coldest state, and dived into the waters of the Derwent which have been a cold 11 levels Celsius.
An hour in, he noticed the primary handfish, however with the burst of his digital camera flash it was gone. All of the {photograph} had captured was a cloud of silt. Remy realized he must hone his method for this species and spent three consecutive days and a complete of 9 hours within the river.
Ultimately, after mastering a particular swimming method together with his flippers that didn’t fire up the silt, and utilizing a distinct sort of lighting gadget that created a slim highlight, Remy received his shot – a close-up of the charismatic fish, with its “fingers” and the fluffy lure in plain sight. The {photograph} went on to win first place within the cold-water class of the Underwater Images Information’s Ocean Artwork 2022 contest.
Remy hopes that his images will assist to shine a light-weight on this uncommon species that most individuals know – and care – little about. Utilizing portrait-style images, he desires to create an emotional reference to the handfish, prompting individuals to get engaged in conserving the “very unusual trying fish.”

Efforts to protect the noticed handfish, and its much more critically endangered family, the purple handfish and Ziebell’s handfish, are ongoing. The Nationwide Handfish Restoration Workforce plans to revive all three species, that are discovered within the waters of south-eastern Australia. Of the purple handfish, solely 100 adults are thought to stay, whereas the Ziebell’s hasn’t been noticed within the wild since 2007.
“Low dispersal functionality, small inhabitants dimension, and comparatively low reproductive output make them vulnerable to environmental disturbance,” says Jemina Stuart-Smith, chair of the Nationwide Handfish Restoration Workforce, who notes habitat loss, air pollution and concrete improvement as main threats. What’s extra, their quirky technique of strolling reasonably than swimming, makes it troublesome for handfish to make use of ocean currents to hold them away from degraded areas, she provides.
Restoration efforts contain monitoring populations of all three species, restoring their pure habitat, eradicating invasive species or over-abundant sea urchins, and dealing with aquariums to ascertain captive breeding packages and insurance coverage populations. Within the Derwent River, the workforce has planted synthetic habitat to encourage noticed handfish spawning, which has already proven promising leads to stabilizing populations, says Stuart-Smith.
However whereas there was some progress, the scenario continues to be pressing and the restoration workforce wants longer-term funding and assets, says Stuart-Smith. She hopes the Australian authorities’s latest threatened species motion plan, which goals to forestall any new extinctions, will assist because the purple handfish is listed within the plan’s 110 precedence species.
Producing consciousness can also be essential to conservation efforts, she says, and images might be an essential medium for this.
Mark Strickland, American photographer and decide of the Ocean Artwork 2022 photograph contest, agrees. He advised CNN in an e mail: “By capturing and sharing stunning photographs of such not often seen species, underwater photographers can play an outsized function by creating consciousness and concern amongst individuals who may in any other case be unaware of the plight being confronted by these species and the delicate habitats the place they reside.”
