Disney has announced it will close all its Florida resort beaches and post new signs warning of alligators -- two days after a Nebraska toddler was attacked and drowned by one of the creatures in a resort lagoon that bore no warning of their dangerous presence. 

"We are also conducting a swift and thorough review of all of our processes and protocols," Disney spokeswoman Jacquee Wahler told the Associated Press in a statement late Thursday night.

The absence of signage throughout the Disney theme parks, located in a state with more than a million gators across all 67 Florida counties, has drawn criticism from legal experts, among others, who say Disney could be held liable for the child's death. Though most Floridians know that alligators live in nearly every fresh water body in the state, experts told The Washington Post it would be reasonable to argue that vacationers coming from somewhere like Nebraska wouldn't share the same knowledge.

The boy, Lane Graves, his parents Matt and Melissa Graves, and a 4-year-old sister had been at Disney for three days, guests at the Grand Floridian Resort and Spa, when they decided to spend Tuesday night relaxing on a narrow patch of beach outside the hotel.

On its website, Disney encourages guests at the Grand Floridian to "bask on the white-sand beach" that abuts the Seven Seas Lagoon.

At around 9 p.m., the toddler walked to the water's edge, where posted signs inform guests that swimming is prohibited but do not warn of alligators. He waded into the murky water, authorities said, about a foot away from the safety of the sand. Vulnerable and appearing like prey, the boy was snatched into the gator's jaws and dragged deeper into the lagoon, said Orange County Sheriff Jerry Demings.

The boy's father, Matt Graves, rushed toward the water after his son, attempting to pry at the alligator's clamped jaws. Graves, who a family friend told Inside Edition was a state championship wrestler, scratched his hands during the struggle, but was unable to retrieve his son.

Sixteen hours later, authorities found the boy's body "completely intact," Demings said at a press conference Wednesday, about six feet beneath the surface of the massive, man-made lagoon that stretches along Disney's Magic Kingdom theme park. His body wasn't far from where the tragedy first unfolded.

An autopsy Thursday determined the child died from drowning and traumatic injuries, reported the Associated Press.

Law enforcement and wildlife officials have said repeatedly since Tuesday that they work diligently with Disney to remove nuisance alligators from waterways inside the park. Disney told the AP that they have a relocation policy for gators considered to be a threat. Those under 4 feet long are moved to conservation areas, the company told the AP, and larger gators are removed by state-licensed trappers.

But some have called Disney's wildlife education efforts into question.

In a phone interview Thursday, Kadie Whalen, of Wynnewood, Pa., told the AP that her children nearly met the same fate as Lane Graves four years ago when her family vacationed at Walt Disney World. Her three young kids and niece were playing on a resort beach at the water's edge, with buckets and shovels provided by Disney employees, when the eyes of a 7-foot alligator peered above the surface, just feet away from the oblivious children.

Whalen screamed, she told the AP, and everyone scattered. Per their policy, trappers came and captured the alligator from the lake outside the Caribbean Beach Resort, Whalen said, but when she complained to the front desk and wrote Disney a letter, she never heard back.

Her concern was that the company knew how prevalent alligators were in their waterways, yet failed to educate guests on the dangers of their presence.

"It never crossed our minds at Disney World that we would have to worry about a predator eating our children," Whalen told the AP. "We don't have alligators in Pennsylvania."

The Graves, from the Omaha area, have not spoken publicly since the attack Tuesday night, asking for privacy in this trying time. Its unclear if the parents knew of the dangers alligators pose in Florida's waterways. They released a statement praising law enforcement efforts to rescue, then recover their son.

"Words cannot describe the shock and grief our family is experiencing over the loss of our son," the Graves family said in a statement, reported ABC News. "To all of the local authorities and staff who worked tirelessly these past 24 hours, we express our deepest gratitude."
