A new report says shark attacks declined in the U.S. last year, but worldwide fatalities reached a two-decade high.
University of Florida released its International Shark Attack File report Tuesday.

According to the report, the U.S. and Florida saw a five-year downturn in the number of reported unprovoked attacks.

But ichthyologist George Burgess says the 12 fatalities -- which all occurred outside the U.S. -- may show tourists are venturing to more remote places with less access to immediate medical care.

The number of deaths in 2011 was twice that of 2010.

A total of 75 attacks were reported worldwide, which is close to the decade average.

Florida led the U.S. with 11 of the nation's 29 attacks. Six of Florida's attacks were in Volusia County.
