A series of cruel wildlife attacks on Western Australia’s South Coast that left pelican’s stabbed, turtles hung and hooked, and a seagull skewered.

While authorities have not ruled out that some of the incidents could have resulted from human littering, the Western Australian Department of Biodiversity, Conservation and Attractions is investigating whether the injuries were deliberate or malicious.

Wildlife Carer Jessica Berry said the trophy like display of these animals is disappointing considering that their larger size often indicates the animals had against the odds survived through to maturity.
