Toxic sea slugs have been reported across Auckland's eastern bays beaches from Okahu Bay to Kohimarama.

For the first time, the sea slugs have been collected from Mission Bay and another has been found in rock pools close to Kelly Tarlton's Underwater World in Orakei.

The Auckland City Council has put up more signs and is closely monitoring beaches.

The sea slugs generally appear at low tide and yesterday was an extremely low tide.

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