Stranded whale disappears from Vic beach

A 2.5 metre whale that was stranded on a Victorian beach has disappeared.

The whale that beached itself on Monday at Logans Beach, east of Warrnambool, was believed to be either a pygmy sperm whale or a dwarf sperm whale, the Department of Environment, Land, Water and Planning says.

A department spokesman told AAP a rescue team returned to help the whale on Tuesday morning but could not find it, so officers would monitor the area in case it reappears.
