The male whale most likely died at sea before it washed ashore on Anthony's beach.
Tasmanian scientists are excited about the number of giant squid beaks found inside a huge sperm whale which beached in the state's north-west.

The 17-metre whale washed up on Anthony's Beach between Smithton and Stanley on Saturday.

Scientists from the Marine Conservation Program examined the carcass on Sunday and believe the mammal died of old age.

Spokesman says the whale's large teeth will be studied to determine its age.

"We think he will probably be between 70 to 80," he said.

The whale was in very good condition and its stomach contained many local species including a large number of giant squid beaks.

"Sperm whales are famous for battling with the giant squid and we've seen lots of evidence of those battles.
