The name of the boy was also released ... 2-year-old Lane Graves from Elkhorn, Nebraska -- and his parents, Matt and Melissa.
The Orange County sheriff said Lane's body was located 10-15 yards from where he was pulled under water ... in about 6 feet of water. They said the body is still intact.
A rep for Fish and Wildlife said they will run forensics on the 5 gators they've pulled out of the Seven Seas Lagoon to determine if one of them is responsible for the child's death. They said if they can't find a match ... they'll continue searching for the culprit.
As we previously reported ... there were no signs warning of alligators in the water at the Disney Resort.
