Stingray







stingray's live in topical coastal waters around the world. Some of this places are Asia, Africa, Florida.These animals are predators, and they eat all types of invertebrates and also fish, that they catch near or upon the bottom of the ocean (or rivers, in the case of the few freshwater species). stingrays breathe the same way that fish do they pass water over there gills and exchanging oxygen from the water. there mating season occurs in the winter. He will follow the female stingray closely, biting at her pectoral disc. they will have a litter witch mean 5 or more stingrays at a time.The female holds the embryos in the womb without a placenta. Instead, the embryos absorb nutrients from a yolk sac, and after the sac is depleted the mother provides uterine milk. stingrays have a Venus sting in the back of their bodies.Indeed their sting can be quite painful, and explorer Steve Irwin was killed by a sting piercing his heart.but at the most part they are berry kind and harmless.
