One of the 12 remaining sloths from Sloth World Orlando – now being cared for and treated at the Central Florida Zoo – has become lethargic and is considered to be in critical condition, the zoo said

Sloth World, a new attraction on Orlando’s I-Drive that was announced last year, imported dozens of the South American mammals, several of which are now dead.

A planned tourist attraction along International Drive has been shut down before ever opening its doors after state investigators say more than 30 sloths died while in the care of the business.

The Central Florida Zoo & Botanical Gardens determined the animals were "dehydrated" upon their arrival, and one animal needed critical care

A planned International Drive attraction called Sloth World will not open following dozens of animal deaths, conservation groups said late Friday, as its 13 remaining sloths were placed in the care of animal experts at Central Florida Zoo & Biological Gardens.

No law required Sloth World operators to report animal deaths to the state, according to the Florida Fish and Wildlife Conservation Commission.

The animal was originally slated to be included in Sloth World, a planned International Drive attraction. It was one of 13 transferred from the planned Sloth World. to Central Florida Zoo.

Many of the deaths were attributed to a lack of heat at an unauthorized warehouse that Sloth World was using, officials said.
