About Lord Howe Abalone
The Lord Howe Abalone (Haliotis rubiginosa) is an exceptionally rare, micro-endemic marine gastropod restricted entirely to the tiny marine park surrounding Lord Howe Island. Entirely bypassed by commercial food markets due to its miniature size, it faces severe modern ecological pressures and is officially listed as Critically Endangered on the IUCN Red List. Climate-induced marine heatwaves pose an existential threat to its highly localised, fragile habitat, prompting strict conservation legalities and hefty penalties to protect this ecologically unique island grazer from disturbance.
