Directly behind the eyes are spiracles, which are openings that allow for respiration. Their tails are typically longer than their disc width and usually have one or more long, saw-like spines behind the pelvic fin. Used for self-defense, the stinger is tipped with barbs that can rip through flesh when withdrawn.
Each spine has grooves underneath that contain protein-based venom. The spines are constantly being shed and replaced, allowing the stingray to sometimes have two stingers as a new stinger grows in to replace the older one.
Most South American species have colorful dorsal patterns that feature spots of different sizes and background colorings of gray, brown or black. Freshwater stingrays can grow to have a disc width of about 18 inches 46 centimeters. Their tails can reach up to 1 foot Freshwater stingray are native to South America.
As their name implies, they live in fresh water in the Amazon. This is in contrast to most cartilaginous fish, which live in a salt water environment. Freshwater stingrays eat crustaceans and other invertebrates.
Their powerful jaws can easily crush the shells of clams and mussels, and they will occasionally eat small fish. At the Smithsonian's National Zoo, the stingrays eat shrimp, earthworms, smelt and an aquatic omnivore gel diet.
Freshwater stingrays reproduce through internal fertilization. A male impregnates the female by using a modified pelvic fin as he bites the female's back. The unborn young are ovoviviparous, meaning they are nourished by egg yolk inside the mother's body. After a gestation period of three months, the female produces eggs that hatch internally before birth. Everywhere Threads This forum This thread. Search Advanced…. New posts. Search forums.
