Card sharks are among the most threatened marine creatures, and they are particularly vulnerable to attack.
The critically endangered species have been listed as a threatened species by the International Union for Conservation of Nature, and are listed as endangered by the World Wildlife Fund, the Australian Parks and Wildlife Service and the Australian government.
In 2018, the Cairns-based Card Sharks Trust and the Caimans Marine Institute were awarded the National Trust of Australia’s Outstanding Conservation Award, which recognises efforts to conserve the species.
A report by the Trust’s scientists found the species had been at risk from overfishing and overfleshing.
Its report also said that card sharks had been found in the Great Barrier Reef, and that there were plans to establish a national marine park in Cairn.
Dr Nicky Young, of the Caulfield Marine Institute, said the number of species listed as threatened under the IUCN Red List was very high.
“We’re really concerned about the impact on our species,” she said.
Ms Young said that the Trust was concerned about how the numbers of card sharks in the waters off Cairndale would be affected by a national park.
There were also concerns about the number and type of corals that were found in Caimens waters, she said, with the report warning that there was a higher likelihood of coralfish or other corals in the Cairs waters than in other areas.
Card sharks can be found in all marine ecosystems, but they are most commonly found in shallow waters close to land.
