*Domain- Southern Stingrays are in the domain EUKARYA because they are multicellular, have membrane bound organelles, and have genetic material inside the nucleus.

*Kingdom- Southern Stingrays are in the kingdom ANAMALIA because they are heterotrophic, lack cell walls, and they are motile at some stage of their life cycle.

*Phylum- Southern Stingrays are a part of the phylum CHORDATA because they have bilateral symmetry, a complete digestive tract, a segmented body, and a coelom. An animal in this phylum also has the following five unique characteristics: a notochord, a dorsal nerve chord, a post anal tail, an endostyle and pharyngeal pouches.

*Class- Southern Stingrays are a part of the class CHONDRICHTHEYES because they are vertebrates, have cartilaginous skeletons and have true jaws. Other organisms that belong to this class include: Great White Sharks, Bull Sharks, Blue-Spotted Stingrays, and Manta Rays.

*Order- Southern Stingrays are a part of the orderSouthern Stingray Photo by Arthur Koch MYLIOBATIFORMS because this order includes the rays that have the venomous spine that gives them the name stingray. Members of this order are ovoviviparous and have a pelvic fin with one lobe.

*Family- Southern Stingrays are a part of the family DASYATIDAE because this family includes the stingrays that have a whiptail.

*Genus- Southern Stingrays are a part of the genus DASYATIS. To find the meaning of this genus, you have to break it up into “dasys” and “batus”. “Dasys” means rough or dense and “batus” means shark.

*Common Name- Dasyatis americana are commonly know as Southern Stingrays or Southern Atlantic Stingrays because they are mainly located in the southern part of the Atlantic Ocean. They get the name stingray because of their venomous spine located on their tail.

    This tree is based on morphological characteristics that separate the different orders of Rays. The Pristiformes are the only rays with a saw-like nose. The Rhinobatiformes and Torpediniformes have their 2 dorsal fins closer to the pelvic fins. Rajiformes and Myliobatiformes usually do not have dorsal fins, but if they do, they would be located closer to the tail tip. Southern Stingrays do not have dorsal fins on their whiptails. The Torpediniformes are known as electric rays because they have electric organs that they use to create an external jolt of electricity to fight off predators. The Myliobatiformes only have one lobe one their pelvic fin. You can find out where the pelvic fin is by visiting the Defenses page.
