Texas Man Catches Fish With Human-Like Teeth
July 19, 2006

A fish caught in Lubbock, Texas, with teeth that look like they belong
to a human has baffled wildlife officials in the area, according to a
report.

Fisherman Scott Curry reeled in the 20-pound fish on Buffalo Springs
Lake and immediately noticed the catch had human-like teeth.

A game warden photographed the fish and is attempting to identify it.

General Manager of Buffalo Springs Lake Greg Thornton told KLBK13-TV
in Texas that he has never seen anything like the fish in the 36 years
he has lived near the lake.

A search for what the fish may be suggested that it may be a pacu,
which is found in South America.

Curry said he believes he saw another similar fish while on the lake.

A Texas television station reported that lake officials will give $100
to anyone catching a similar fish.
