NASHVILLE, Tenn. (AP) - State wildlife biologists aren't sure how three sharks and an octopus turned up recently in Tennessee waters.

The sharks, identified as black nose or fine tooth species, were found dead in the Tennessee River in the Decatur County area over a span of 9 days in mid-March.

The octopus was found dead last week in Watts Bar Lake near Chattanooga.

Bobby Wilson, assistant chief of fisheries for the Tennessee Wildlife Resources Agency, told The Tennessean newspaper it was probably a hoax.

It is illegal to place any fish in public waters in Tennessee. The penalty is $50 plus court costs and up to 30 days in jail.
