Warning for Augusta residents as toxic ‘slug’ sea hares return to coast

Dog owners are on notice after hundreds of toxic sea hares once again washed up in Augusta last week.

Up to 700 of the toxic slug-like creatures appeared on beaches as well as lower parts of the Hardy Inlet, the including Jays Beach dog exercise area, Colourpatch and Ellis Street Jetty.

A Shire of Augusta-Margaret River spokesperson said the marine slugs posed a serious threat to dogs, potentially causing seizures, vomiting and even death if eaten or even if dogs come into contact with the creatures’ toxic slime or ink.

The mass stranding was a semi-regular late-summer event which had put residents on notice previously.

The biggest sea hare stranding occurred in 2021 and created serious problems for local dogs.

“These creatures carry toxins, and even a small lick or contact with their slime or purple ink can be harmful to dogs,” the spokesperson said.

Other warning signs included tremors and seizures, vomiting, excessive drooling, spasms, agitation and difficulty walking.

The Department of Primary Industries and Regional Development and Department of Water and Environmental Regulation were on alert and beaches were being monitored.
