More toxic slugs appearing across Eastern Bays beaches

Toxic sea slugs are being reported across Eastern Bays beaches from Okahu Bay to Kohimarama prompting Auckland City Council to erect more signs and caution beachgoers to supervise their children and pets.

For the first time, the sea slugs have been collected from Mission Bay and another has been found in rock pools close to Kelly Tarltons.

The council is closely monitoring beaches and officers are distributing cautionary leaflets.

The sea slugs generally appear at low tide and today (Wednesday) was an extremely low tide.

Environmental health manager Chris Dee said there appears to be a relationship between strong on-shore winds and the appearance of the creatures.

"Last year they appeared between July and October and were absent for the rest of the year, suggesting some relationship between their appearance and their life cycle," he said.

The poison from the slugs is very toxic to dogs and potentially toxic to humans.

Further sightings should be reported immediately to the council. If you find one and can safely collect it, using a plastic bag or container, do so making sure you do not touch it and thoroughly wash hands afterwards. Alternatively, mark the spot and leave it well alone. An environmental health officer will remove it safely.
