Rays 
Stingrays are freshwater fish that have cartilaginous skeleton and belong to the family of sharks.
Are feared by humans because they have located sting in the tail, where they release a poison painful and which are used when they feel threatened or being harassed.
Females are larger and heavier than males, due to the width of your disk to be related to the amount (not size) of children they may generate.
The male has two testes that produce sperm and two copulatory organs called clasp that are located in the ventral part in a folding of the pelvic fin.
The female has two ovaries, two uteri has assets that can accommodate 1-19 embryos (depending on the species and age) at different stages of development, is able to store sperm and the vagina ends in a common cloaca.
Mating is usually nocturnal and at the time of flood the rivers, and during sex the male bites the female and holds it with his jaw. Gestation lasts 3-9 months, and reproduction is regulated by the hydrological cycle.
Pregnant women to miscarry easily be molested or taken in an attempt to provide the survival of some more mature embryo.
The vast majority of females give birth during the rainy season, the cubs are born with a stinger and not to hurt the mother, are expelled from the uterus and the embryo's head rolled out of himself.
This fish has maternal care, and after childbirth, the mother stays with the chicks in the back protecting them from predators for three to five days.
The freshwater stingrays are captured or killed in the Brazilian Amazon because of the ornamental trade, or trade of consumption or the negative practice of fishing, which is the practice of killing streak and cut its tail in order to prevent the sting mainly on the beaches used for ecotourism, where does the "cleaning of the river beaches" before the arrival of tourists.
