A humpback whale that took a wrong turn into a crocodile-infested river in Australia has safely returned to sea.
Three humpback whales were spotted in the East Alligator River in Kakadu National Park, located in Australia’s Northern Territory.
It is the first known instance of humpback whales in the river.
One of the whales appeared to have gotten stuck in the river, home to a large number of saltwater crocodiles.
The whale had apparently gotten lost after becoming confused during migration, said the national park.
Saltwater crocodiles are ambush predators that have been known to attack and kill humans.

The crocodiles can stay hidden under water for long periods and can move with great stealth and camouflage.
Given its large size, the humpback had been considered unlikely to be disturbed by crocodiles unless it became stranded.
“The last thing we want is a collision between a boat and whale in waters where crocodiles are prevalent and visibility underwater is zero,” Parks Australia had added in a statement.
