A dolphin has been rescued after getting stranded in shallow waters in Melbourne's Port Phillip Bay.
Water police were called to Greenwich Reserve, Williamstown, about 4pm on Monday by marine animal experts from Melbourne Zoo.
Two inflatable rescue boats carrying four officers were sent out and a sling was made to tow the marooned mammal into deeper water.
Animal experts assessed the dolphin before it was successfully released.
"Our members often see dolphins in the bay during patrols and it's great to see this one back where it belongs," Leading Senior Constable Tony Christensen said.
"We hope to cross paths again - but this time well away from shore."
