Marine life marooned in Tasmania

According to a report published today by The Times newspaper, conservationists in Australia have deemed the stranding of 200 whales and dolphins on Naracoopa Beach in Tasmania, ‘suspicious’.
Wildlife rescue teams and local people were able to save and return to the ocean, 54 whales and five dolphins, though the remainder of the 192 creatures had died before the rescue teams could reach them.
A thorough enquiry into the mass stranding has been requested by conservationists due to fears that the root cause may be human disturbance, citing ‘industrial activity’ and the ‘use of military sonar devices’ as prime suspects.
Another possibility to the cause of the marooned animals is climate change - with the changes in water temperature causing whales and dolphins to divert from their usual routes and travel into ‘unchartered territory’, namely near to unknown coastlines.
However, mass stranding may be linked to group behaviour, and the ‘follow the leader’ psychology of these species. It may simply be a natural event, the result of a ‘navigational error’.
The Times continues to state that Tasmania may account for 80% of all Australian strandings, with four significant incidents having occurred in recent months.
