The life cycle of a stingray is similar to the life cycles of most other living organisms.  It is born, usually as part of a litter, ranging from five to ten.  It grows to reproductive size and continues to propagate the ray species.  Stingrays are ovoviviparous, meaning the mother nourishes the unborn baby rays inside her body, without the benefit of a placenta.  Instead, the babies draw nourishment from the mother via a yolk sac.

Stingrays often feed on the bottom, leaving only their eyes and tails visible.  They populate coral reefs, and share this area with sharks during high tide.  Their main diet is mollusks, shellfish, and occasionally, small fish.

Stingrays are edible, the main part being the wings.  They may be caught with line or spear.  While not valuable as a food source, their removal may be ordered as they interfere with other sources of fish wildlife.

Stingrays are primarily located in warm, tropical waters.  If threatened, they will flee, trying to avoid conflict, but will use their stinging barb for self-defense.  The barb is sharp and contains venom, which causes discomfort, but is not lethal unless stabbed in a vital area.
