A summer vacation took a turn for the worse when a mommy influencer's young daughter was attacked by a shark in Florida - leaving her without her right hand.

Leah Lendel, nine, was snorkeling off the shore of Boca Grande with her mother Nadia and her siblings around noon on June 11, when she was bitten by the shark.

Bystanders said an eight-foot bullshark managed to bite off the girl's right hand and part of her wrist. She emerged from the water on her own, completely covered in blood.

With the help of nearby construction workers, the family called 911 and created a tourniquet out of a beach towel to stop the bleeding.

Lendel, with her father, was airlifted to Tampa, 100 miles away and admitted for emergency surgery in hopes of reattaching the hand.
