Three Shark Attacks in a Single Day Injure Swimmers on Florida's Gulf Coast

Authorities close beaches and increase patrols after a woman and two teenage girls are severely injured in separate incidents.

A 45-year-old woman lost part of her arm and suffered critical injuries while swimming near WaterSound Beach.
Two teenage girls were attacked in waist-deep water less than two hours later at Seacrest Beach, leaving one in critical condition.
Local authorities closed beaches temporarily and are using boats to patrol the waters for increased safety.
Experts note that shark attacks are rare, but Florida leads in the number of shark bites worldwide.
Small fish traveling near the shore may have contributed to the unusual frequency of attacks.
