Australia's Ariarne Titmus has won the silver medal in the women's 800-metres freestyle at the Tokyo Olympics.
Titmus' second place in Saturday's final won by American Katie Ledecky gives the Australian a fourth medal of the Games.
It follows her wins in the 200m and 400m freestyles and a bronze in the 4x200m freestyle relay.
The Australian could also add another in the 4x100 medley relay final on Sunday.
In the 800m freestyle final, Titmus and the rest of the field were unable to counter Ledecky, who won the event for a third consecutive Olympics to claim a seventh career gold medal.
The American won in eight minutes 12.57 seconds from Titmus (8:13.83) and Italian Simona Quadarella (8:18.35).
Australia's Kiah Melverton (8:22.25) finished sixth.
