Near the Calakmul Biosphere Reserve in southern Mexico, there's a spot the locals call Volcán de los Murciélagos—the Volcano of Bats. There are no real volcanoes in the area, but there is a deep limestone cave that's home to eight different species of bats, with totals numbering several million. When dusk falls, the bats "erupt" in a swirling, clockwise stream as they flee from the cave and out into the night. Tropical entomologist and TV host Phil Torres recently visited the site with the Rainforest Alliance, which is doing conservation work in the area, to film the bats in all their crepuscular glory.

The FDA has recalled several brands of dry dog food that contain potentially toxic levels of vitamin D, The Atlanta Journal-Constitution reports. While vitamin D is essential for dogs, too much of the nutrient can result in kidney failure and other serious health problems.

The FDA has already received reports of vitamin D toxicity in dogs that consumed certain dry foods. Pet owners are advised to stop using the following products:

Symptoms of vitamin D poisoning usually develop 12 to 36 hours after pets consume a suspect food, according to PetMD. The FDA says those symptoms include vomiting, loss of appetite, increased thirst, increased urination, excessive drooling, and weight loss. "Customers with dogs who have consumed this product and are exhibiting these symptoms should contact their veterinarian as soon as possible," the FDA writes.

The agency says the situation is still developing, and it will update the list of recalled brands as more information becomes available. According to WKRN News, veterinary professionals recommend sticking to dog foods that have an AAFCO label (from the Association of American Feed Control Officials) on them.
