Stingrays
Stingrays are cartilaginous fish related to sharks that have barbed stingers on their tails used for self-defense. They have flattened bodies and use smell and electroreception to find prey like small fish and invertebrates buried in the sea floor since they cannot see prey under them. There are several families of stingrays described in the document with varying physical characteristics like number of gills or shape of pectoral fins.

- 2. Stingrays are agroup of rays, which are cartilaginous fish related to sharks and consist of about seven major families. Most stingrays have one or more barbed stingers on the tail, which are used exclusively in self-defense. The flattened bodies of stingrays allow them to effectively conceal themselves in their environment. Because their eyes are on top of their bodies and their mouths on the undersides, stingrays cannot see their prey; instead, they use smell and electroreceptors similar to those of sharks. A stingray's diet includes small fish, snails, clams, shrimp, and some other small sea creatures.
- 3. The Sixgill Stingrayis a species of stingray and the only remaining member of the family Hexatrygonidae. The Sixgill Stingray has a bulky, flabby body with a rounded pectoral fin disc that is longer than wide, and a long, triangular snout. The tiny eyes are placed far apart, and unlike other stingrays, the sixgill has six gills instead of the usual five. The disc is purplish to pinkish brown above, darkening slightly at the fin margins.
- 4. The Deepwater Stingrayis a species of stingray and the sole member of the family Plesiobatidae. The Deepwater Stingray has a flabby body, with enlarged pectoral fins forming a disc usually longer than it is wide. The snout is thin and protrudes slightly from the disc. The Deepwater Stingray is purplish brown to blackish above; some rays also have irregular darker blotches and spots. The underside is white.
- 5. The Urolophidae isa family of rays commonly known as Stingarees. They are sluggish, bottom-dwelling fish. Stingarees have relatively large, venomous stinging spines on their tail, with which they can inflict a painful wound on humans. They are modestly sized and have greatly enlarged pectoral fins fused to the head, forming a disc that may be nearly circular, to oval, to rhomboid in shape. The snout is usually short and does not protrude much from the disc. Stingarees are generally shades of yellow, green, brown or gray above and pale below; some species are plain, while others are adorned with spots, rings, blotches, lines, or more complex patterns.

- 7. Dasyatidae is alsoknown as the Whiptail Stingrays. Members of this family have flattened pectoral fin discs that range from oval to diamond-like in shape. Their common name comes from their whip-like tails, which are much longer than the disc and lack dorsal and caudal fins. All whiptail stingrays, except the porcupine ray, have one or more venomous barbs near the base of the tail, which are used in defense. Leopard Whiptail

- 9. River stingrays areNeotropical freshwater fishes of the Potamotrygonidae family. They are generally pale brown, variously mottled or speckled, and have venomous caudal barbs. They are one of the most feared freshwater fishes in the Neotropical region, sometimes more feared than piranhas and electric eels. However, they are not dangerous unless stepped on or otherwise threatened. River stingrays are the only family of stingray completely restricted to fresh water habitats. This famiy also contains the third largest freshwater fish in the world, the Mekong “giant” river stingray. Rosette River Stingray

- 13. The eagle raysare a group of cartilaginous fishes in the family Myliobatidae, consisting mostly of large species living in the open ocean rather than on the sea bottom. They are excellent, powerful swimmers and are able to breach the water up to several meters above the surface. Compared with other rays, they have long tails, and well-defined rhomboidal bodies. Most are quite large in size and have some of the most popular stingrays. Giant Manta (Manta Ray)
