Whale Shark & Manta Ray

The Whale Shark (Rhincodon typus) is the largest non- terrestrial (land) animal on the planet! They are huge, reaching a length of 32 feet (about 9.7 meters!) in adulthood, with unconfirmed reports of them being even larger than that.

They live in tropical and warm waters of the oceans around the world. They are considered a vulnerable species, despite a general 70 year life span in the wild.
 They feed on plankton and microscopic mammals. They are quite incapable of eating larger prey, as their throat is only about as large around as an American Quarter dollar (smaller than a Canadian loonie). Whale sharks are only found in one zoo out side of the orient, the Georgia Aquarium in Atlanta Georgia.

The Manta Ray has two subspecies: the Reef Manta Ray (Manta alfredi) and the Giant Ocean Manta Ray (Manta birostris). The Giant Ocean Manta Ray are the largest ray species in the world, reaching a size of approximately 23 feet (7 meters) or more. The Reef Manta Ray are a bit smaller, getting up to 11 feet (3.5 meters).

The Giant Ocean Manta Ray is found in tropical and warm waters, the world over. They feed on plankton and microscopic sea life.
 They are considered a vulnerable species. Only four aquariums in the world feature manta rays, and the Georgia Aquarium in Atlanta, Georgia is one of those four!

 
Both the Whale Shark (3 whale sharks, actually), and the Giant Ocean Manta Ray can be seen in Georgia Aquariums 6.3 MILLION GALLON exhibit called 'Ocean Voyages'.
