Beachgoers have been urged to be on the lookout for bluebottles.
Reports of bluebottles on Surf Coast beaches last week and several sightings near Ocean Grove mean beachgoers should be on the lookout.
Bluebottles are frequently seen along the east coast of Australia during summer months although are not usually as common in southern and western Victoria
The sudden appearance of large numbers of bluebottles are a consequence of prevailing winds and currents over previous days and weeks pushing these animals through the water, some of which wash up on beaches.
Bluebottles can deliver a painful sting even when washed up dead on the beach.
Bluebottle tentacles will cause a sharp, painful sting if they are touched, which is aggravated by rubbing the area.
If stinging occurs, leave the water immediately. Wash off any adherent tentacles with salt water.
