A Sydney beach looked more like a Jaws scene, as red patches filled the sea in a popular vacation spot.
Male residents should not worry, there is no killer shark in the waters, but they have been advised to avoid swimming in the affected area.
The reddish and stained water is a flowering seaweed, a WaterNSW spokesperson told the Daily Telegraph.
Manly resident Keryn Hill said she "got a bit of a shock" when she saw the red tide while she hung up her clothes.
He said that the proliferation of algae has been identified as noctiluca scintillansan, which is not known to produce toxins, however, should be avoided as a precautionary measure.
The flowers are often visible as a red discoloration in the water and can produce bioluminescence at night when it bothers them, he said.
Manly resident Keryn Hill said she was "a little surprised" when she saw the red tide while hanging her clothes.
"It's definitely not a dark pink, it looks like blood."
It was the second time this month that a strange color was discovered in the waters near Manly.
A pink spot was discovered in the waters of Manly Cove and Shelly Beach on August 15, the Manly Daily reported.
